circuit output is an open collector type with
output
This circuit monitors output voltage, and when output
voltage is below the specified minimum causes the
output transistor to be in the ON (saturation)
state. When the output voltage is above the specified level,
this circuit permits the

output transistor to go into
Delay circuit.
RESET
This circuit provides a programmable (by external capaci-
tor) delay on the
output lead. The Delay lead pro-
vides source current to the external delay capacitor only
when the "Low Voltage Inhibit" circuit indicates that out-
put 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 a controlled
pulse is generated following
detection of an error condition. The circuit allows
the
output transistor to go to the OFF (open) state
only when the voltage on the Delay lead is higher than
