LM9073

Dual High Current Low-Dropout System Regulator

General Description

Features

n Two 5V regulated outputs:

The LM9073 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% tolerance 5V output at 700mA with a low dropout charac-

teristic. 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 (igni-

tion or battery potentials in automotive applications) which

makes it suitable for powering remotely located load circuits

or sub-systems.

700mA, 2% Main output

100mA, 2% External Supply output

n External Supply output protected from shorts to battery

n Good EMI (1MHz to 400MHz, BCI) immunity

n Separate ON/OFF and Keep-Alive control inputs

n Less than 100µA quiescent current in OFF state

n Programmable delayed reset output

n Adjustable threshold voltage for generating reset

n Built-in system watchdog timer

n Input transient protection over 60V to −45V

n Less than 1V dropout at full load

The LM9073 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

Alive input whereby a system can remain powered after igni-

tion has been switched OFF. Additionally, a watchdog func-

tion is built in to enhance system operationally reliability.

n Wide −40˚C to 125˚C operating temperature range

n Surface mount, TO−263 and standard TO−220 power

packages

Applications

n Automotive module supply power conditioning

n Remote sub−system powering

n Continuous operation for save routines and E²PROM

programing after power down command

n Safety relates systems − EMC operational with a system

watchdog monitor

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.
