LM9071

Low-Dropout System Voltage Regulator with Delayed

Reset

General Description

Features

n Automotive application reliability

n 3% output voltage tolerance

n Insensitive to radiated RFI

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.

n Dropout voltage less than 800 mV with 250 mA output

current

n Externally programmed reset delay interval

n Thermal shutdown

n Short circuit protection

n Reverse battery protection

n Wide operating temperature range −40˚C to +125˚C

n TO-220 and TO-263 power surface mount power

packages

n Pin for pin compatible with the LM2927, L4947 and

TLE4260

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).
