Automotive 300mA LDO Voltage Regulators

with Tracker Output and Overvoltage Protector

8/MAX510

General Description

Features

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.

♦ 300mA LDO Regulator, Voltage Tracker, and OVP

Controller (MAX15008)

♦ 300mA LDO Regulator and Voltage Tracker

(MAX15010)

♦ 50mA Voltage Tracker with 3mV Tracking Accuracꢀ

♦ 5V to 40V Wide Operating Supplꢀ Voltage Range

♦ 45V Load Dump Protection

♦ 70µA Quiescent Current LDO Regulator

♦ OVP Controller Disconnects or Limits Output from

Batterꢀ Overvoltage Conditions (MAX15008)

♦ LDO Regulator with Enable, Hold, and Reset

The 300mA LDO regulator consumes less than 70µA 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

timeout period.

The voltage tracker accurately ( 3mV) tracks a voltage

applied to its input from either the LDO output or an exter-

nal source. It can supply up to 50mA of current to a

remote sensor, allowing for precise ratiometric tracking in

automotive applications. A separate enable input turns

the tracker on or off, reducing supply current when the

tracker is unused. The voltage tracker also features pro-

tection against battery reversal, an output short circuit to

the battery, or an output-voltage excursion below ground

potential to as much as -5V.

√

The MAX15008 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.
