LM9076
150mA Ultra-Low Quiescent Current LDO Regulator with
Delayed Reset Output
LM9076 150mA Ultra-Low Quiescent Current LDO Regulator with Delayed Reset Output
General Description
The LM9076 is a ±3%, 150 mA logic controlled voltage regulator. The regulator features an active low delayed reset
output flag which can be used to reset a microprocessor system at turn-ON and in the event that the regulator output
voltage falls below a minimum value. An external capacitor
programs a delay time interval before the reset output pin can
return high.
Designed for automotive and industrial applications, the
LM9076 contains a variety of protection features such as
thermal shutdown, input transient protection and a wide operating temperature range. The LM9076 uses an PNP pass
transistor which allows low drop-out voltage operation.
