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.
