V
IN
ENABLE
Supply voltage to IC, usually direct from the battery.
CMOS compatible logical input. V
OUT
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 V
OUT
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 V
OUT
.
No connection
