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
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 k resistor
Sense output; the open collector output is connected to Q1
via an integrated 30 k resistor
Stand-by regulator output voltage; block to GND with a
capacitor
Main regulator adjust input; Q2 can be set to higher
values than 5 V by an external voltage divider from Q2 to
GND
Main regulator output voltage; block to GND with a
capacitor
Ground
Main regulator input voltage; block to GND directly at the
IC with a ceramic capacitor
