DT

GND

Reset Delay Time Select. Short to GND or connect to Vout to select time.

Power Supply Ground.

7

RO

Reset Output. 30 kW internal Pull−Up resistor connected to Vout. RO goes Low when Vout drops by more

than 7% (typ.) from its nominal value.

8

SO

Early Warning Output. 30 kW internal Pull−Up resistor connected to Vout. It can be used to provide early

warning of an impending reset condition. Leave open if not used.

9

Vout

Regulated Output Voltage. Connect 2.2 mF capacitor with ESR < 100 W to ground.

13

Vin

Positive Power Supply Input. Connect 0.1 mF capacitor to ground.

14

SI

Sense Input; If not used, connect to Vout. See Electrical Characteristics Table and Application Information

sections for more information.
