General Description

The MAX8836Z high-frequency step-down converter is optimized to provide a fixed output voltage with ultralow dropout.

The device integrates a high-efficiency PWM step-down converter for medium- and low-power transmission, and a 60mΩ typical bypass FET for ultra low-dropout operation.

A 200mA low-noise, high-PSRR low-dropout regulator (LDO) is also integrated.
