Symbol
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. Use a low pass filter if transients with slew
rate in excess of 10 V/ms may be present on this pin during operation. See Figure 40 for details.
7
RO
Reset Output. NPN collector output with internal 20 k pullup to Q. Notifies user of out of regulation
condition.
8
SO
Sense Output. NPN collector output with internal 20 k 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 F, ESR
5.0 to ground.

I
Input. Battery Supply Input Voltage.
14
SI
Sense Input. Can provide an early warning signal of an impending reset condition when used with SO.
