LM9072  
Dual Tracking Low-Dropout System Regulator  
General Description  
Features  
n Two 5V regulated outputs:  
— 350 mA, 2% Main output  
— 80 mA, 1.5% Tracking output  
The LM9072 is a high performance voltage regulator system  
with operational and protection features that address many  
requirements of automotive applications. Two regulated out-  
puts are provided. The main regulator provides a precision  
2% maximum tolerance 5V output at 350 mA with a low drop-  
out characteristic. The second regulator provides a 5V out-  
put that tracks the main regulator output voltage within 1.5%  
with load currents up to 80 mA. 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 unregu-  
lated input supply (ignition or battery potentials in automotive  
applications).  
n Good EMI (1 MHz to 400 MHz, BCI) immunity  
n Separate ON/OFF and Keep-Alive control inputs  
n Less than 100 µA quiescent current in OFF state  
n Programmable delayed reset output  
n Input transient protection over 60V to −45V  
n Tracking output protected from shorts to battery  
n Less than 1V dropout at full load  
n −40˚C to +125˚C operating temperature range  
n Surface mount TO-263 Power Package and Standard  
TO-220 power package  
The LM9072 also contains a programmable delayed system  
reset output. Two control inputs are provided. An ON/OFF in-  
put intended for connection to an ignition switch, and a Keep Typical Applications  
Alive input to allow a system to remain powered after ignition  
has been switched OFF.  
n Automotive module supply power conditioning  
n Remote sensor biasing  
For EMC concerns the LM9072 remains fully operational  
and does not generate false rest signals while subjected to,  
1 MHz to 400 MHz bulk current injection signals greater than  
100 mA on the input supply and tracking output lines.  
n Ratiometric to supply sensor detection  
n Continuous operation for save routines and EPROM  
programming after power down command  
n Safety related systems — EMC operational
