LM9071
Low-Dropout System Voltage Regulator with Delayed
Reset
General Description
The LM9071 is a 5V, 250 mA low-dropout voltage regulator.
The regulator features an active low delayed reset output
flag which can be used to reset a microprocessor system on
turn-ON and in the event that the regulator output falls out of
regulation for any reason. An external capacitor programs a
delay time interval before the reset output can return high.
Designed for automotive application the LM9071 contains a
variety of protection features such as reverse battery,
over-voltage shutdown, thermal shutdown, input transient
protection and a wide operating temperature range.
Design techniques have been employed to allow the regula-
tor to remain operational and not generate false reset signals
when subjected to high levels of RF energy (300V/m from
2 MHz to 400 MHz).
