200mA, Automotive, Ultra-Low
Quiescent Current, Linear Regulator
General Description
Features
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.
