SNVS134D –DECEMBER 1999–REVISED APRIL 2013  
LM9072 Dual Tracking Low-Dropout System Regulator  
Check for Samples: LM9072

FEATURES  
DESCRIPTION  
The LM9072 is a high performance voltage regulator  
system with operational and protection features that  
address many requirements of automotive  
2
•
Two 5V Regulated Outputs:  
–
–
350 mA, 2% Main Output  
80 mA, 1.5% Tracking Output  
applications. Two regulated outputs are provided. The  
main regulator provides a precision 2% maximum  
tolerance 5V output at 350mA with a low dropout  
characteristic. The second regulator provides a 5V  
output that tracks the main regulator output voltage  
within 1.5% with load currents up to 80mA. The  
tracking output is ideal for use in powering remotely  
located sensors with outputs that are ratiometric to  
the main system supply. This output is fully protected  
from short circuits to ground or the unregulated input  
supply (ignition or battery potentials in automotive  
applications).  
•
•
Good EMI (1 MHz to 400 MHz, BCI) Immunity  
Separate ON/OFF and Keep-Alive Control  
Inputs  
•
Less Than 100 μA Quiescent Current in OFF  
State  
•
•
•
Programmable Delayed Reset Output  
Input Transient Protection Over 60V to −45V  
Tracking Output Protected From Shorts to  
Battery  
•
•
•
Less Than 1V Dropout at Full Load  
The LM9072 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 to allow a  
system to remain powered after ignition has been  
switched OFF.  
−40°C to +125°C Operating Temperature Range  
Surface Mount SFM Power Package  
TYPICAL APPLICATIONS  
•
Automotive Module Supply Power  
Conditioning  
For EMC concerns the LM9072 remains fully  
operational and does not generate false rest signals  
while subjected to, 1MHz to 400 MHz bulk current  
injection signals greater than 100 mA on the input  
supply and tracking output lines.  
•
•
•
Remote Sensor Biasing  
Ratiometric to Supply Sensor Detection  
Continuous Operation for Save Routines and  
EPROM Programming After Power Down  
Command  
•
Safety Related Systems—EMC Operational
