FUNCTION

Supply voltage to IC, usually direct from the battery.

CMOS compatible logical input. VOUT is disabled i.e.

placed in a high impedance state when ENABLE is high.

Ground connection.

CMOS compatible output lead. RESET goes low when-

ever VOUT falls out of regulation. The RESET delay is

externally programmed.

Regulated output voltage, 5V (typ).

Kelvin Connection which allows remote sensing of out-

put voltage for improved regulation. If remote sensing is

not desired, connect to VOUT.

No connection
