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 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-circuit protected and includes thermal shutdown.
The MAX5091 operates over the -40°C to +125°C automotive temperature range and is available in 8-pin, thermally enhanced TDFN and SO-EP packages.
