Input. Battery Supply Input Voltage. Bypass directly to GND with ceramic capacitor.
Sense Input. Can provide an early warning signal of an impending reset condition when used with SO.
Connect to Q if not used.
Reset Adjust. Use resistor divider to Q to adjust reset threshold lower. Connect to GND if not used.
Reset Delay. Connect external capacitor to ground to set delay time.
Ground.
Reset Output. NPN collector output with internal 20 kW pullup to Q. Notifies user of out of regulation
condition. Leave open if not used.
Sense Output. NPN collector output with internal 20 kW pullup to Q. Can be used to provide early warning
of an impending reset condition. Leave open if not used.
5.0 V, 3.3 V, "2%, 150 mA output. Use 22 mF, ESR t 5.0 W to ground.
