RESET/ENABLE
Supply voltage to IC, usually direct from battery.
Regulated output voltage 5V, 500mA (typ) switched.
Ground connection.
CMOS compatible output lead, RESET goes low whenever
V
OUT1
becomes unregulated. To use the ENABLE option, con-
nect the lead via a resistor to V
IN
(see app. notes).
STANDBY output 5V, 10mA typ, always on.
