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).
