Pin Function
VIN is the supply pin for the LDO. A small 1 mF ceramic
bypass capacitor is required between the V
near the device. When using longer connections to the power
supply, C
operating input voltage range is from 2.3 V to 5.5 V.
EN is the enable control logic (active high) for the regulator
output. It has a 2.5 MW pull−down resistor, which assures
that if EN pin is left open, the circuit is disabled.
VOUT is the LDO regulator output. A small 1 mF ceramic
bypass capacitor is required between the V
ground for stability. For better transient response, its value
can be increased to 4.7 mF.
Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
NOTE:
1. The maximum allowable power dissipation at any T
2. The device is not guaranteed to work outside its operating rating.

The capacitor should be located near the device. ESR
domain is 5 mW to 500 mW. V
guaranteed current of 300 mA. For input−to−output voltages
higher than 1 V, a continuous 300 mA output current might
turn−on the thermal protection. A 250 W internal shutdown
switch discharges the output capacitor in the no−load
condition.
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 mF
capacitor can be connected between BYP pin and GND to
reduce the output noise and enhance the PSRR at high
frequency.
