Regulator Input. Bypass IN to GND with a 0.1µF capacitor.
Ground. This pin also functions as a heatsink. Solder to large pads or
the circuit-board ground plane to maximize thermal dissipation.
Active-Low Shutdown Input. Connect SHDN to V
operation.
Active-Low Reset Output. RESET remains low while V
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.
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
(typ) to V
Regulator Output. Bypass OUT to GND with a minimum 3.3µF (min)
low-ESR capacitor.
Regulator Input. Bypass IN to GND with a 0.1µF capacitor.
Ground. This pin also functions as a heatsink. Solder to large pads or
the circuit-board ground plane to maximize thermal dissipation.
Active-Low Shutdown Input. Connect SHDN to V
operation.
Active-Low Reset Output. RESET remains low while FB is below the
reset threshold. 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.
Feedback Input for Linear Regulator Controller or Remote Sense
Applications. Connect FB to the external load (V
output voltage.
Regulator Output. Bypass OUT to GND with a minimum 3.3µF low-ESR
capacitor.
