Pin

Symbol

Function

1

RADJ

Reset Threshold Adjust

connect an external voltage divider to adjust reset threshold;

connect to GND for using internal threshold

2, 6

n.c.

not connected

leave open or connect to GND

3D

Reset Delay Timing

connect a ceramic capacitor to GND for adjusting the reset delay time;

leave open if the reset function is not needed

4

GND

Ground

connect all pins to PCB and heatsink area

5EN

Enable

high signal enables the regulator;

low signal disables the regulator;

connect to I if the Enable function is not needed

7RO

Reset Output

open collector output; internally linked to the output via a 20k

Ω pull-up resistor;

leave open if the reset function is not needed

8SO

Sense Output

open collector output; internally linked to the output via a 20k

Ω pull-up resistor;

leave open if the sense comparator is not needed
