MAX5091AATA+T-MAX5091BATA+T
28V, 100mA, Low-Quiescent-Current LDO with Reset and Power-Fail Input/Output
General Description
The MAX5091 high-voltage linear regulator is designed to
operate from a +5V to +28V input voltage, and withstands up to 40V transients. The device consumes only 45μA of quiescent current at 100μA output current. The MAX5091
delivers up to 100mA of output current with low 50mV
maximum dropout voltage. The MAX5091 provides an
active-low open-drain microprocessor RESET output. The
reset timeout period is programmable and can be set with
an external capacitor. The MAX5091 includes an uncom-
mitted comparator for input voltage monitoring/power-
fail indication. The device is available with a fixed +5V
(MAX5091A) or +3.3V (MAX5091B) output. The MAX5091
is short-circuit protected and includes thermal shutdown.
The MAX5091 operates over the -40°C to +125°C auto-
motive temperature range and is available in 8-pin, ther-
mally enhanced TDFN-EP and SO-EP packages.

Absolute Maximum Ratings
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.
