Automotive 300mA LDO Voltage Regulators
with Tracker Output and Overvoltage Protector
General Description
The MAX15008 features a 300mA LDO regulator, a volt-
age tracker, and an overvoltage protection (OVP) con-
troller to protect downstream circuits from high-voltage
load dump. The MAX15010 includes only the 300mA
LDO voltage regulator and voltage tracker. Both devices
operate over a wide 5V to 40V supply voltage range and
are able to withstand load-dump transients up to 45V. The
MAX15008/MAX15010 feature short-circuit and thermal-
shutdown protection. These devices offer highly integrat-
ed power-management solutions for automotive
applications such as instrument clusters, climate control,
and a variety of automotive power-supply circuits.
The 300mA LDO regulator consumes less than 67μA qui-
escent current at light loads and is well suited to power
always-on circuits during “key off” conditions. The LDO
features independent enable and hold inputs as well as a
microprocessor (μP) reset output with an adjustable reset

potential to as much as -5V.
The MAX15008 OVP controller operates with an external
enhancement mode n-channel MOSFET. While the moni-

the OVP threshold, the OVP controller quickly turns off the
