FUNCTION
Regulator Input. Supply voltage can range from +2.25V to +5.5V. Bypass with a 1 μ F capacitor to GND (see
Capacitor Selection and Regulation Stability ). 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 0.02 μ A. 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 10 μ F low-ESR capacitor to GND.
Connect both OUT pins together externally.
