IO ± Output Current ± mA

Because the PMOS pass element behaves as a

low-value resistor, the dropout voltage is very low

± maximum of 85 mV at 100 mA of load current

Output 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 A 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 A maximum at TJ = 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, 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).

²Minimum 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:

VI(min) + VO(max) )VDO(max load)

Because the TPS7201 is programmable, rDS(on) should be used to calculate VDO before applying the above equation. The equation for calculating VDO from rDS(on) is given in Note 3 under the TPS7201 electrical characteristics table. The minimum value of 3 V is the absolute lower limit for the recommended input-voltage range for the TPS7201.

²CSR refers to the total series resistance, including the ESR of the capacitor, any series resistance added externally, and PWB trace resistance to CO.

³Pulse-testing techniques are used to maintain virtual junction temperature as close as possible to ambient temperature; thermal effects must be taken into account separately.

§ This voltage is not recommended.

¶ Output voltage programmed to 2.5 V with closed-loop configuration (see application information).

NOTES: 2. When VI < 2.9 V and IO > 100 mA simultaneously, pass element rDS(on) increases (see Figure 10) to a point such that the resulting dropout voltage prevents the regulator from maintaining the specified tolerance range.

3. To calculate dropout voltage, use equation:

VDO = IO rDS(on)

rDS(on) is a function of both output current and input voltage. The parametric table lists rDS(on) for VI = 2.4 V, 2.9 V, 3.9 V, and 5.9 V, which corresponds to dropout conditions for programmed output voltages of 2.5 V, 3 V, 4 V, and 6 V, respectively. For other

programmed values, refer to Figures 10 and 11.
