Description
1
RADJ
Reset Adjust. Use resistor divider to Q to adjust reset threshold lower. Connect to GND if not used.
2
D
Reset Delay. Connect external capacitor to ground to set delay time.
3
GND
Ground.
4
GND
Ground.
5
GND
Ground.
6
INH
Inhibit. Connect to I if not needed. A high turns the regulator on.
7
RO
Reset Output. NPN collector output with internal 20 kW pullup to Q. Notifies user of out of regulation condi-
tion.
8
SO
Sense Output. NPN collector output with internal 20 kW pullup to Q. Can be used to provide early warning
of an impending reset condition.
9
Q
5.0 V, 3.3 V, "2%, 150 mA output. Use 22 mF, ESR t 5.0 W to ground.
