Function

Reset switching threshold adjust; for setting the reset

switching threshold connect to a voltage divider from Q1 to

GND. If this input is connected to GND, the reset is

triggered at the internal threshold.

Reset delay; connect a capacitor CD to GND for delay time

adjustment

Disable input main regulator; Q2 disabled with high signal

Ground

Reset output; the open collector output is connected to Q1

via an integrated 30 kΩ resistor

Sense output; the open collector output is connected to Q1

via an integrated 30 kΩ resistor

Stand-by regulator output voltage; block to GND with a

capacitor CQ1 ≥ 6 µF, ESR < 10 Ω at 10 kHz

Main regulator adjust input; Q2 can be set to higher

values by an external divider

Main regulator output voltage; block to GND with a

capacitor CQ2 ≥ 10 µF, ESR < 10 Ω at 10 kHz

Ground

Main regulator input voltage; block to GND directly at the

IC with a ceramic capacitor

Stand-by regulator input voltage; block to GND directly at

the IC with a ceramic capacitor
