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

•

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
