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
regulator 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).
