LM9070 Low-Dropout System Voltage Regulator with Keep-Alive ON/OFF Control  
Check for Samples: LM9070

FEATURES  
DESCRIPTION  
The LM9070 is a 5V, 3% accurate, 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.

Externally Programmed Reset Delay Interval  
Keep-Alive Feature with 2 Logic Control Inputs  
60V Load Dump Transient Protection  
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 protection and a wide  
operating temperature range.  
Short Circuit Protection and Disable Safety  
Features  
A unique two-input logic control scheme is used to  
enable or disable the regulator output. An ON/OFF  
input can be provided 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).

Lead Form Compatible with TLE4267 TO-220  
Regulator  
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).
