45V, 400mA, Low-Quiescent-Current

Linear Regulator with Adjustable Reset Delay

General Description

Features

♦ Wide Operating Input Voltage Range (6.5V to 45V)

♦ Thermally Enhanced Package Dissipates

The MAX5087 high-voltage linear regulator operates

from an input voltage of 6.5V to 45V and delivers up to

400mA of output current. The device consumes only

70µA of quiescent current with no load and 11µA in

shutdown. The device includes a SET input, that when

connected to ground, selects a preset output voltage of

3.3V (MAX5087A) or 5.0V (MAX5087B). Alternatively,

the output voltage can be adjusted from 2.5V to 11V by

simply connecting SET to the regulator’s output through

a resistive divider network. The MAX5087 also provides

an open-drain, active-low microprocessor (µP) reset

output that asserts when the regulator output drops

below the preset output voltage threshold. An external

capacitor programs the reset timeout period. Other fea-

tures include an enable input, thermal shutdown, and

short-circuit protection.

♦ Guaranteed 400mA Output Current

♦ 70µA Quiescent Supply Current

♦ Preset 3.3V, 5.0V, or Adjustable 2.5V to 11V

Output Voltage

♦ Remote Load Sense Capability

♦ Enable Input

♦ Integrated µP Reset Circuit with Programmable

Timeout Period

♦ Thermal and Short-Circuit Protection

♦ -40°C to +125°C Operating Temperature Range

The MAX5087 operates over the automotive tempera-

ture range of -40°C to +125°C and is available in a 16-

pin TQFN thermally enhanced package.
