150mA Ultra-Low Quiescent Current LDO Regulator with Delayed Reset Output
National Semiconductor
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.
