LM9073 Dual High Current Low-Dropout System Regulator
PRELIMINARY
April 2000
LM9073
Dual High Current Low-Dropout System Regulator
General Description
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.
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.
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.
