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 20kΩ 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 20kΩ pull-up resistor;
leave open if the sense comparator is not needed
9, 10, 12 n.c. not connected
leave open or connect to GND
11 Q Output
block to GND with a capacitor close to the IC terminals, respecting the values given for
its capacitance C
Q
and ESR in the table “Functional Range” on Page 8
13
I
Input
for compensating line influences, a capacitor to GND close to the IC terminals is
recommended
14 SI Sense Input
connect the voltage to be monitored;
connect to Q if the sense comparator is not needed
PAD – Exposed Pad
attach the exposed pad on package bottom to the heatsink area on circuit board;
connect to GND
