NAME
FUNCTION
11
IN
Regulator Input. Supply voltage can range from 2.5V to 5.5V. Bypass with 2.2
F
capacitor to GND (see Capacitor Selection and Regulator Stability).
2
GND
Ground
33
SHDN
Active-Low Shutdown Input. A logic low reduces the supply current to below 0.1
A.
In shutdown, POK and OUT are driven low. Connect to IN for normal operation.
—
4POK
Open-Drain Active-Low POK Output. POK remains low while the output voltage (VOUT) is
below the reset threshold. Connect a 100k
pullup resistor to OUT to obtain a logic level
output. POK is driven low in shutdown. If not used, leave this pin unconnected.
4
—
BP
Reference Bypass. Bypass with a low-leakage 0.01
F ceramic capacitor.
5
OUT
Regulator Output. Sources up to 300mA guaranteed. Bypass with 2.2
F (<0.2 typical
ESR) ceramic capacitor to GND.
