circuit output is an open collector type with
ON and OFF parameters as specified. The
NPN transistor is controlled by the two circuits described

output
The Low Voltage Inhibit Circuit monitors output voltage,
and when output voltage is below the specified minimum,
causes the
output transistor to be in the ON (satu-
ration) state. When the output voltage is above the speci-
fied level, this circuit permits the
to go into the OFF state if allowed by the

RESET
The Reset Delay Circuit provides a programmable (by
external capacitor) delay on the
Delay lead provides source current to the external delay
capacitor only when the Low Voltage Inhibit circuit indi-
cates that output voltage is above V
RT(ON)
. Otherwise, the
Delay lead sinks current to ground (used to discharge the
delay capacitor). The discharge current is latched ON
when the output voltage is below V
RT(OFF)
. The Delay
capacitor is fully discharged anytime the output voltage
falls out of regulation, even for a short period of time. This
feature ensures that a controlled

allows the
output transistor to go to the OFF (open)
