PIN
NAME
FUNCTION
1, 2
IN
Regulator Input. Supply voltage can range from +2.5V to +5.5V. Bypass with a 1
μ
F capacitor to GND (see
Capacitor Selection and Regulator Stability
). Connect both input pins together externally.
3
RST
Open-Drain Active-Low Reset Output.
RST
remains low while the output voltage (V
OUT
) is below the reset
threshold and for at least 4ms after V
OUT
rises above the reset threshold. Connect a 100k
pullup resistor
to OUT to obtain an output voltage.
4
SHDN
Active-Low Shutdown Input. A logic low reduces supply current to 0.1
μ
A. In shutdown, the
RST
output is
low and OUT is pulled low through an internal 5k
resistor. Connect 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 to GND for preset output. Connect to a resistive divider between OUT and
GND to set the output voltage between 1.25V and 5.0V.
7, 8
OUT
Regulator Output. Sources up to 500mA. Bypass with a 3.3
μ
F low-ESR capacitor to GND. Use a 4.7
μ
F
capacitor for output voltages below 2V. Connect both output pins together externally.
