LM9070  
Low-Dropout System Voltage Regulator with Keep-Alive  
ON/OFF Control  
General Description  
Features  
n Automotive application reliability  
The LM9070 is a 5V, 3% accurate, 250 mA low-dropout  
voltage regulator. The regulator features an active low de-  
layed reset output flag which can be used to reset a micro-  
processor 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 3% output voltage tolerance  
n Insensitive to radiated RFI  
n Dropout voltage less than 800 mV with 250 mA output  
current  
n Externally programmed reset delay interval  
n Keep-alive feature with 2 logic control inputs  
n 60V Load dump transient protection  
n Thermal shutdown  
Designed for automotive application the LM9070 contains a  
variety of protection features such as reverse battery, over-  
voltage shutdown, thermal shutdown, input transient protec-  
tion and a wide operating temperature range.  
n Short circuit protection and disable safety features  
n Reverse battery protection  
A unique two-input logic control scheme is used to enable or  
disable the regulator output. An ON/OFF input can be pro-  
vided by an ignition switch derived signal while a second,  
Keep-Alive input, is generated by a system controller. This  
allows for a system to remain ON after ignition has been  
switched OFF. The system controller can then execute a  
power-down routine and after which command the regulator  
OFF to a low quiescent current state (60 µA max).  
n Low OFF quiescent current, 50 µA maximum  
n Wide operating temperature range −40˚C to +125˚C  
n TO-263 and 20-pin power surface mount packages  
n Lead form compatible with TLE4267 TO-220 regulator  
(package TA07D)  
Design techniques have been employed to allow the regu-  
lator 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).
