Figure 2. Adjustable Output LDO
EN is the enable control logic (active high) for the regulator
output. It has a 2.5 M W pull ? down resistor, which assures
that if EN pin is left open, the circuit is disabled.
VOUT is the LDO regulator output. A small 2.2 m F ceramic
bypass capacitor is required between the VOUT pin and

ground. For better transient response, its value can be
increased to 4.7 m F.
The capacitor should be located near the device. For the
SOT23-5 package, a continuous 500 mA output current may
turn-on the thermal protection. A 250 W internal shutdown
switch discharges the output capacitor in the no-load
condition.
TAB To be connected to the ground plane on PCB
Pin Function
VIN is the supply pin for the LDO. A small 1 m F ceramic
bypass capacitor is required between the V IN pin and ground
near the device. When using longer connections to the power
supply, C IN value can be increased without limit. The
operating input voltage range is from 2.3 V to 5.5 V.
Table 2. ABSOLUTE MAXIMUM RATINGS
GND is the ground reference for the LDO. The pin must be
connected to the ground plane on the PCB.
BYP is the reference bypass pin. An optional 0.01 m F
capacitor can be connected between BYP pin and GND to
reduce the output noise and enhance the PSRR at high
frequency.
ADJ is the adjustable input pin for the adjustable LDO. The
pin is connected to the resistor voltage divider.

NOTE: Typical application circuit with external components is shown above.
1. The maximum allowable power dissipation at any T A (ambient temperature) is P Dmax = (T Jmax ? T A )/ q JA . Exceeding the maximum allowable
power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
2. The device is not guaranteed to work outside its operating rating.
