Pin Description
PIN
NAME
FUNCTION
1, 2
IN
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.
3
POK
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.
4
SHDN
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.
5
GND
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.
6
SET
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.
7, 8
OUT
Regulator Output. OUT sources up to 500mA. Bypass OUT with a 10μF low-ESR capacitor to GND.
Connect both OUT pins together externally.
