NAME
FUNCTION
IN
Regulator Input. Bypass IN to GND with a 0.1μF capacitor.
2
3
A2
GND
Ground. This pin also functions as a heatsink. Solder to large pads or
the circuit-board ground plane to maximize thermal dissipation.
3

A3
SHDN
Active-Low Shutdown Input. Connect
SHDN
to V
IN
for normal
operation.

C3
RESET
Active-Low Reset Output.
RESET
remains low while V
OUT
is below the
reset threshold or while
MR
is held low.
RESET
remains low for the
duration of the reset timeout period after the reset conditions are
terminated.
RESET
is available in open-drain and push-pull
configurations.

C2
MR
Active-Low Manual Reset Input. The reset output is asserted while
MR
is pulled low and remains asserted for the duration of the reset timeout
period after
MR
transitions from low to high. Leave
MR
unconnected or
connect to V
OUT
if not used.
MR
has an internal pullup resistor of 40k
(typ) to V
OUT
.

C1
OUT
Regulator Output. Bypass OUT to GND with a minimum 3.3μF (min)
low-ESR capacitor.
