A1  
IN  
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.

GND  
SHDN Active-Low Shutdown Input. Connect SHDN to V for normal operation.  
IN  
Active-Low Reset Output. RESET remains low while V  
is below the  
OUT  
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.

RESET  
Feedback Input for Externally Setting the Output Voltage. Connect SET  
to GND to select the preset output voltage. Connect SET to an external  
resistor-divider network for adjustable output operation.

SET  
OUT  
Regulator Output. Bypass OUT to GND with a minimum 3.3µF low-ESR  
capacitor.  
7, 8  
EP  
Exposed Paddle. EP is internally connected to GND. Connect EP to the  
ground plane to provide a low thermal-resistance path from the IC  
junction to the PCB. Do not use as the electrical connection to GND.
