Symbol Function
1
RADJ
Reset Threshold Adjust
Connect an external voltage divider to adjust reset threshold;
Connect to GND for using internal threshold.
3
D
Reset Delay
Connect a ceramic capacitor from D (Pin 3) to GND for reset delay time adjustment;
Leave open, if the reset function is not needed.
4
GND
Ground
Connect to heat sink area.
5
EN
Enable
High signal enables the regulator;
Low signal disables the regulator;
Connect to I if the enable function is not needed

RO
Reset Output
Open collector output with an internal pull-up resistor to the output Q;
An additional external pull-up resistor to the output Q is optional;
Leave open if the reset function is not needed.
8
SO
Sense Output
Open collector output with an internal pull-up resistor to the output Q;
An additional external pull-up resistor to the output Q is optional;
Leave open if the sense function is not needed.

5 V Regulator Output
Connect a capacitor between Q (Pin 11) and GND close to the IC pins, respecting the
values given for its capacitance C_Q and ESR in the table Chapter 4.2 Functional Range.
Regulator Input and IC Supply
For compensating line influences, a capacitor to GND close to the IC pin is
recommended.
14
SI
Sense Input
Connect the voltage rail to be monitored;
Connect to Q if the sense comparator is not needed.
