Pin Function
Reference Bypass: Connect external 0.01F 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.
