Description
+2.0V to +5.5V Supply Voltage. Bypass this pin with a 1µF capacitor to GND (see
Capacitor Selection and Regulator Stability on page 11).
1
IN
Open-Drain POK Output. POK remains low while VOUT is below the POK
threshold. Connect a 100kΩ pull-up resistor from this pin to OUT to obtain an output
voltage (see Figure 1 on page 1).
2
POK
Active-High Enable Input. A logic low reduces supply current below 30nA. In
shutdown mode, the POK output is low, and OUT is high impedance. Connect this
pin to IN for normal operation.

EN
Ground
GND
SET
Voltage-Setting Input. Connect to GND for preset output or Connect to a resistive
voltage-divider between OUT and GND to set the output voltage between 1.2V and
5.3V (see Figure 1 on page 1).
Bypass Pin. Connect a 10nF capacitor from this pin to VOUT to improve PSRR and
noise performance (see Figure 16 on page 9).

BYP
OUT
Output. Sources up to 500mA. Bypass this pin with a 2.2µF low-ESR capacitor to
GND (see Figure 1 on page 1).
Note: For output voltages below 2V a 4.7µF capacitor should be used.
