DESCRIPTION
The REG104 is a family of low-noise, low-dropout linear regulators with low ground pin current. Its new DMOS topol­ogy provides significant improvement over previous designs, including low dropout voltage (only 230mV typ at full load), and better transient performance. In addition, no output capacitor is required for stability, unlike conventional low dropout regulators that are difficult to compensate and require expensive low ESR capacitors greater than 1µF.
Typical ground pin current is only 1.7mA (at I drops to 0.5µA in
not enabled
mode. Unlike regulators with PNP pass devices, quiescent current remains relatively con­stant over load variations and under dropout conditions.
The REG104 has very low output noise (typically 33µV for V
= 3.3V with CNR = 0.01µF), making it ideal for use
OUT
in portable communications equipment. On-chip trimming results in high output voltage accuracy. Accuracy is main­tained over temperature, line, and load variations. Key pa­rameters are tested over the specified temperature range (–40°C to +85°C).
The REG104 is well protected—internal circuitry provides a current limit which protects the load from damage. Thermal protection circuitry keeps the chip from being damaged by excessive temperature. The REG104 is available in the DDPAK-5 and the SOT223-5.

ELECTROSTATIC DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Texas Instru­ments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(2) Dropout voltage is defined as the input voltage minus the output voltage that produces a 2% change in the output voltage from the value at V
at fixed load. (3) Not applicable for V (4) Current limit is the output current that produces a 15% change in output voltage from V (5) For V (6) The REG104 no longer regulates when V

BASIC OPERATION
The REG104 series is a family of LDO (Low DropOut) linear regulators. The family includes five fixed output versions (2.5V to 5.0V) and an adjustable output version. An internal DMOS power device provides low dropout regulation with near constant ground pin current (largely independent of load and dropout conditions) and very fast line and load transient response. All versions include internal current limit and thermal shutdown circuitry.
Figure 1 shows the basic circuit connections for the fixed voltage models. Figure 2 gives the connections for the adjustable output version (REG104A) and example resistor values for some commonly used output voltages. Values for other voltages can be calculated from the equation shown in Figure 2.

None of the versions require an output capacitor for regulator stability. The REG104 will accept any output capacitor type less than 1µF. For capacitance values larger than 1µF the effective ESR should be greater than 0.1. This minimum ESR value includes parasitics such as printed circuit board traces, solder joints, and sockets. A minimum 0.1µF low ESR capacitor connected to the input supply voltage is recom­mended.
ENABLE
The Enable pin allows the regulator to be turned on and off. This pin is active HIGH and compatible with standard TTL­CMOS levels. Inputs below 0.5V (max) turn the regulator off and all circuitry is disabled. Under this condition ground-pin current drops to approximately 0.5µA.
When not used, the Enable pin may be connected to V Internal to the part, the Enable pin is connected to an input resistor-zener diode circuit, as shown in Figure 3, creating a nonlinear input impedance.

The REG104 utilizes an internal charge pump to develop an internal supply voltage sufficient to drive the gate of the DMOS pass element above V
. The charge-pump switching
IN
noise (nominal switching frequency = 2MHz) is not measur­able at the output of the regulator.
DROP-OUT VOLTAGE
The REG104 uses an N-channel DMOS as the ment. When the input voltage is within a few hundred millivolts of the output voltage, the DMOS device behaves like a resistor. Therefore, for low values of V regulators input-to-output resistance is the Rds DMOS pass element (typically 230m). For static (DC) loads, the REG104 will typically maintain regulation down to V

voltage drop of 230mV at full rated output current.

TRANSIENT RESPONSE
The REG104 response to transient line and load conditions improves at lower output voltages. The addition of a capaci­tor (nominal value 10nF) from the output pin to ground may improve the transient response. In the adjustable version, the addition of a capacitor, C
(nominal value 10nF), from the
FB
output to the adjust pin will also improve the transient response.
THERMAL PROTECTION
Power dissipated within the REG104 will cause the junction temperature to rise. The REG104 has thermal shutdown circuitry that protects the regulator from damage. The ther­mal protection circuitry disables the output when the junc­tion temperature reaches approximately 150°C, allowing the device to cool. When the junction temperature cools to approximately 130°C, the output circuitry is again enabled. Depending on various conditions, the thermal protection circuit may cycle on and off. This limits the dissipation of the regulator, but may have an undesirable effect on the load.
Any tendency to activate the thermal protection circuit indi­cates excessive power dissipation or an inadequate heat sink. For reliable operation, junction temperature should be limited to 125°C, maximum. To estimate the margin of safety in a complete design (including heat sink), increase the ambient temperature until the thermal protection is triggered. Use worst-case loads and signal conditions. For good reli­ability, thermal protection should trigger more than 35°C above the maximum expected ambient condition of your application. This produces a worst-case junction temperature of 125°C at the highest expected ambient temperature and worst-case load.
The internal protection circuitry of the REG104 has been designed to protect against overload conditions. It was not intended to replace proper heat sinking. Continuously run­ning the REG104 into thermal shutdown will degrade reliabil­ity.

The REG104 is available in two different package configura­tions. The ability to remove heat from the die is different for each package type and, therefore, presents different consid­erations in the printed circuit board (PCB) layout. The PCB area around the device that is free of other components moves the heat from the device to the ambient air. While it is difficult to impossible to quantify all of the variables in a thermal design of this type, performance data for several configurations are shown in Figure 9. In all cases the PCB copper area is bare copper, free of solder resist mask, and not solder plated. All examples are for 1-ounce copper. Using heavier copper will increase the effectiveness in moving the heat from the device. In those examples where there is copper on both sides of the PCB, no connection has been provided between the two sides. The addition of plated through holes will improve the heat sink effectiveness.
Power dissipation depends on input voltage and load condi­tions. Power dissipation is equal to the product of the aver­age output current times the voltage across the output element, V
Power dissipation can be minimized by using the lowest possible input voltage necessary to assure the required output voltage.

REGULATOR MOUNTING
The tab of both packages is electrically connected to ground. For best thermal performance, the tab of the DDPAK sur­face-mount version should be soldered directly to a circuit­board copper area. Increasing the copper area improves heat dissipation. Figure 10 shows typical thermal resistance from junction to ambient as a function of the copper area for the DDPAK. Figure 11 shows the same relationship for the SOT-223.

Although the tabs of the DDPAK and the SOT-223 are electrically grounded, they are not intended to carry any current. The copper pad that acts as a heat sink should be isolated from the rest of the circuit to prevent current flow through the device from the tab to the ground pin.
