PIN FUNCTION DESCRIPTION − SO−8 PACKAGE
Pin Symbol
Description
1 I Input. Battery Supply Input Voltage. Bypass directly to GND with ceramic capacitor.
2 SI Sense Input. Can provide an early warning signal of an impending reset condition when used with SO.
Connect to Q if not used.
3
RADJ
Reset Adjust. Use resistor divider to Q to adjust reset threshold lower. Connect to GND if not used.
4 D Reset Delay. Connect external capacitor to ground to set delay time.
5
GND
Ground.
6 RO Reset Output. NPN collector output with internal 20 kW pullup to Q. Notifies user of out of regulation condi-
tion. Leave open if not used.
7 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. Leave open if not used.
8 Q 5.0 V, 3.3 V, "2%, 150 mA output. Use 22 mF, ESR t 5.0 W to ground.
