FEATURES  
DESCRIPTION  
The LM9073 is a high performance voltage regulator  
system with operational and protection features that  
address many requirements of automotive  
2
•
•
•
•
Two 5V Regulated Outputs:  
700mA, 2% Main Output  
100mA, 2% External Supply Output  
applications. Two regulated outputs are provided. The  
main regulator provides a precision 2% tolerance 5V  
output at 700mA with a low dropout characteristic.  
The second output, an External Supply regulator,  
provides a 5V output with 2% tolerance for load  
currents up to 100mA. This External Supply output is  
fully protected from short circuit to ground or the  
unregulated input supply (ignition or battery potentials  
in automotive applications) which makes it suitable for  
powering remotely located load circuits or sub-  
systems.  
External Supply Output Protected from Shorts  
to Battery  
•
•
Good EMI (1MHz to 400MHz, BCI) Immunity  
Separate ON/OFF and Keep-Alive Control  
Inputs  
•
Less than 100µA Quiescent Current in OFF  
State  
•
•
Programmable Delayed Reset Output  
Adjustable Threshold Voltage for Generating  
Reset  
The LM9073 also contains a programmable delayed  
system reset output. Two control inputs are provided.  
An ON/OFF input intended for connection to an  
ignition switch, and a Keep Alive input whereby a  
system can remain powered after ignition has been  
switched OFF. Additionally, a watchdog function is  
built in to enhance system operationally reliability.  
•
•
•
•
Built-in System Watchdog Timer  
Input Transient Protection Over 60V to −45V  
Less than 1V Dropout at Full Load  
Wide −40°C to 125°C Operating Temperature  
Range  
For EMC concerns the LM9073 remains fully  
operational and does not generate false rest signals  
while subjected to greater than 100mA, 1MHz to  
400MHz bulk current injection signals on the input  
supply and External Supply output lines.
