Automotive 300mA LDO Regulators with
Switched Output and Overvoltage Protector
General Description
The MAX15009 includes a 300mA LDO regulator, a
switched output, and an overvoltage protection (OVP)
controller to protect downstream circuits from high-volt-
age load dump. The MAX15011 includes only the 300mA
LDO regulator and switched output. Both devices operate
over a wide supply voltage range from 5V to 40V and are
able to withstand load-dump transients up to 45V. The
MAX15009/MAX15011 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 67μA quiescent
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 adjustable
reset timeout period.
The switched output of the MAX15009/MAX15011
incorporates a low R DS(ON) (0.28 Ω , typ) pass transistor
switch internally connected to the output of the LDO

autoretry timeout.
The MAX15009 OVP controller operates with an external
enhancement mode n-channel MOSFET. While the moni-
tored voltage remains below the adjustable threshold, the
MOSFET stays on. When the monitored voltage exceeds
the OVP threshold, the OVP controller quickly turns off the
external MOSFET. The OVP controller is configurable as a
load-disconnect switch or a voltage limiter.
