The MAX5091BASA+ 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 MAX5091BASA+ delivers up to 100mA of output current with low 50mV maximum dropout voltage. The MAX5091BASA+ provides an active-low open-drain microprocessor RESET output. The reset timeout period is programmable and can be set with an external capacitor. The MAX5091BASA+ 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 MAX5091BASA+ is short-circuit protected and includes thermal shutdown.
The MAX5091BASA+ operates over the -40°C to +125°C automotive temperature range and is available in 8-pin, thermally enhanced TDFN and SO-EP packages.
