No Connection.

VIN

Supply voltage to IC, usually direct from the battery.

CMOS compatible logical. VOUT is disabled i.e. placed in a

high impedance state when ENABLE is high.

Gnd

Ground connection.

CMOS compatible output lead.

VOUT falls out of regulation. The

delay is externally

programmed.

VOUT

Regulated output voltage, 5V (typ).

7VOUT(SENSE)

Remote sensing of output voltage.
