low dropout voltages and quiescent currents compared to conventional LDO regulators. Offered in small-outline integrated-circuit (SOIC) packages and 8-terminal thin shrink small-outline (TSSOP), the TPS72xx series devices are ideal for cost-sensitive designs and for designs where board space is at a premium.

A combination of new circuit design and process innovation has enabled the usual pnp pass

transistor to be replaced by a PMOS device. Because the PMOS pass element behaves as a low-value resistor, the dropout voltage is very low

Figure 1. Typical Dropout Voltage Versus

Output Current

– maximum of 85 mV at 100 mA of load current (TPS7250) – and is directly proportional to the load current (see Figure 1). Since the PMOS pass element is a voltage-driven device, the quiescent current is very low (300 µA maximum) and is stable over the entire range of output load current (0 mA to 250 mA). Intended for use in portable systems such as laptops and cellular phones, the low-dropout voltage and micropower operation result in a significant increase in system battery operating life.

The TPS72xx also features a logic-enabled sleep mode to shut down the regulator, reducing quiescent current to 0.5 µA maximum at T

= 25°C. Other features include a power-good function that reports low output voltage

and may be used to implement a power-on reset or a low-battery indicator. The TPS72xx is offered in 2.5-V , 2.75-V

, 3-V , 3.3-V , 4.85-V, and 5-V fixed-voltage versions and in an adjustable version (programmable over the range of 1.2 V to 9.75 V). Output voltage tolerance is specified as a maximum of 2% over line, load, and temperature ranges (3% for adjustable version).

†

Minimum input voltage defined in the recommended operating conditions is the maximum specified output voltage plus dropout voltage at the maximum specified load range. Since dropout voltage is a function of output current, the usable range can be extended for lighter loads. To calculate the minimum input voltage for the maximum load current used in a given application, use the following equation:

Because the TPS7201 is programmable, r calculating VDO from r lower limit for the recommended input-voltage range for the TPS7201.

SLVS102F – MARCH 1995 – REVISED NOVEMBER 1998

APPLICATION INFORMATION

The design of the TPS72xx family of low-dropout (LDO) regulators is based on the higher-current TPS71xx family . These new families of regulators have been optimized for use in battery-operated equipment and feature extremely low dropout voltages, low supply currents that remain constant over the full-output-current range of the device, and an enable input to reduce supply currents to less than 0.5 µA when the regulator is turned off.

device operation

The TPS72xx uses a PMOS pass element to dramatically reduce both dropout voltage and supply current over more conventional PNP-pass-element LDO designs. The PMOS transistor is a voltage-controlled device that, unlike a PNP transistor, does not require increased drive current as output current increases. Supply current in the TPS72xx is essentially constant from no-load to maximum.

Current limiting and thermal protection prevent damage by excessive output current and/or power dissipation. The device switches into a constant-current mode at approximately 1 A; further load increases reduce the output voltage instead of increasing the output current. The thermal protection shuts the regulator off if the junction temperature rises above 165°C. Recovery is automatic when the junction temperature drops approximately 5°C below the high temperature trip point. The PMOS pass element includes a back diode that safely conducts reverse current when the input voltage level drops below the output voltage level.

A logic high on the enable input, EN EN

should be grounded in applications where the shutdown feature is not used.

Power good (PG) is an open-drain output signal used to indicate output-voltage status. A comparator circuit continuously monitors the output voltage. When the output drops to approximately 95% of its nominal regulated value, the comparator turns on and pulls PG low.

Transient loads or line pulses can also cause activation of PG if proper care is not taken in selecting the input and output capacitors. Load transients that are faster than 5 µs can cause a signal on PG if high-ESR output capacitors (greater than approximately 7 Ω) are used. A 1-µs transient causes a PG signal when using an output capacitor with greater than 3.5 Ω of ESR. It is interesting to note that the output-voltage spike during the transient can drop well below the reset threshold and still not trip if the transient duration is short. A 1-µs transient must drop at least 500 mV below the threshold before tripping the PG circuit. A 2-µs transient trips PG at just 400 mV below the threshold. Lower-ESR output capacitors help by reducing the drop in output voltage during a transient and should be used when fast transients are expected.

A typical application circuit is shown in Figure 31.

, shuts off the output and reduces the supply current to less than 0.5 µA.

external capacitor requirements

Although not required, a 0.047-µF to 0.1-µF ceramic bypass input capacitor , connected between IN and GND and located close to the TPS72xx, is recommended to improve transient response and noise rejection. A higher-value electrolytic input capacitor may be necessary if large, fast-rise-time load transients are anticipated and the device is located several inches from the power source.

An output capacitor is required to stabilize the internal feedback loop. For most applications, a 10-µF to 15-µF solid-tantalum capacitor with a 0.5-Ω resistor (see capacitor selection table) in series is sufficient. The maximum capacitor ESR should be limited to 1.3 Ω to allow for ESR doubling at cold temperatures. Figure 32 shows the transient response of a 5-mA to 85-mA load using a 10-µF output capacitor with a total ESR of 1.7 Ω.

A 4.7-µF solid-tantalum capacitor in series with a 1-Ω resistor may also be used (see Figures 27 and 28) provided the ESR of the capacitor does not exceed 1 Ω at room temperature and 2 Ω over the full operating temperature range.

sense-pin connection

SENSE must be connected to OUT for proper operation of the regulator. Normally this connection should be as short as possible; however, remote sense may be implemented in critical applications when proper care of the circuit path is exercised. SENSE internally connects to a high-impedance wide-bandwidth amplifier through a resistor-divider network, and any noise pickup on the PCB trace will feed through to the regulator output. SENSE must be routed to minimize noise pickup. Filtering SENSE using an RC network is not recommended because of the possibility of inducing regulator instability.

APPLICATION INFORMATION

output voltage programming

The output voltage of the TPS7201 adjustable regulator is programmed using an external resistor divider as shown in Figure 33. The output voltage is calculated using:

Where

= 1.188 V typ (the internal reference voltage)

ref

Resistors R1 and R2 should be chosen for approximately 7-µA divider current. Lower value resistors can be used but offer no inherent advantage and waste more power. Higher values should be avoided as leakage currents at FB increase the output voltage error. The recommended design procedure is to choose R2 = 169 kΩ to set the divider current at 7 µA and then calculate R1 using:

APPLICATION INFORMATION

power dissipation and junction temperature

Specified regulator operation is assured to a junction temperature of 125°C; the maximum junction temperature allowable to avoid damaging the device is 150°C. These restrictions limit the power dissipation that the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, P to P

The maximum-power-dissipation limit is determined using the following equation:

D(max)

, and the actual dissipation, PD, which must be less than or equal

D(max)

Where

max is the maximum allowable junction temperature, i.e.,150°C absolute maximum and 125°C

recommended operating temperature.

θJA

SOIC and 238°C/W for the 8-terminal TSSOP. T

is the ambient temperature.

The regulator dissipation is calculated using:

PD+

Power dissipation resulting from quiescent current is negligible.

is the thermal resistance junction-to-ambient for the package, i.e., 172°C/W for the 8-terminal

regulator protection

The TPS72xx PMOS-pass transistor has a built-in back diode that safely conducts reverse currents when the input voltage drops below the output voltage (e.g., during power down). Current is conducted from the output to the input and is not internally limited. If extended reverse voltage is anticipated, external limiting might be appropriate.

The TPS72xx also features internal current limiting and thermal protection. During normal operation, the TPS72xx limits output current to approximately 1 A. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the package. If the temperature of the device exceeds 165°C, thermal-protection circuitry shuts it down. Once the device has cooled, regulator operation resumes.
