FUNCTION
Regulator Input. Supply voltage can range from 2.25V to 5.5V. Bypass with a 1μF capacitor to GND (see
the Capacitor Selection and Regulation Stability section). Connect both input pins together externally.
Open-Drain, Active-Low Power-OK Output. POK remains low while the output voltage (V OUT ) is below the
POK threshold. Connect a 100k ? pullup resistor from POK to OUT.
Active-Low Shutdown Input. A logic low at SHDN reduces supply current to 0.02μA. In shutdown, the POK
output is low. Connect SHDN to IN for normal operation.
Ground. This pin and the exposed pad also function as a heatsink. Solder both to a large pad or to the
circuit-board ground plane to maximize power dissipation.
Voltage-Setting Input. Connect SET to GND for preset output. Connect an external resistive voltage-divider
from OUT to SET to set the output voltage between 0.8V and 4.5V. The SET regulation voltage is 800mV.
Regulator Output. OUT sources up to 500mA. Bypass OUT with a 10μF low-ESR capacitor to GND.
Connect both OUT pins together externally.
