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 with-
stands 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 programma-
ble and can be set with an external capacitor. The
MAX5091 includes an uncommitted 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-cir-
cuit 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,
thermally enhanced TDFN and SO-EP packages.
