Pin Function
Reference Bypass. Connect external 0.01µF capacitor to GND to reduce output noise. May be left
open.
Delay Set Input. Connect external capacitor to GND to set the delay of the Error Flag.
Ground.
Supply Input.
Regulator Output.
No Connect.
RESET Output. Open-drain output. Active low indicates an output undervoltage condition.
Enable Input: CMOS-compatible input. Logic high = enable; Logic low = shutdown. Do not leave
open.
