200mA, Automotive, Ultra-Low

Quiescent Current, Linear Regulator

General Description

The MAX16910 ultra-low quiescent current, high-voltage

linear regulator is ideal for use in automotive and battery-

operated systems. The device operates from a +3.5V to

+30V input voltage, delivers up to 200mA of load cur-

rent, and consumes only 20µA of quiescent current at

no load. The device consumes only 1.6µA current when

in shutdown. The input is +45V transient tolerant and is

designed to operate under load-dump conditions. The

MAX16910 can be configured as either fixed output volt-

age (+3.3V or +5V) or adjustable output voltage using an

external resistive divider.

The MAX16910 features an open-drain, active-low RESET

output with fixed thresholds offered at 92.5% and 87.5%

of the output voltage. The RESET output remains low for

a fixed period of 60µs after the output voltage exceeds

its threshold. The RESET delay can be extended with an

external capacitor.

The MAX16910 includes an enable input, short-circuit

protection, and thermal shutdown. The MAX16910 oper-

ates over the -40°C to +125°C automotive temperature

range. The device is available in a space-saving, ther-

mally enhanced, 3mm x 3mm, 8-pin TDFN package and

5mm x 4mm, 8-pin SO package.
