General Description

The MAX5084/MAX5085 high-voltage linear regulators operate from an input voltage range of 6.5V to 65V and deliver up to 200mA of output current. These devices consume only 50µA (typ) of quiescent current with no load and 6µA (typ) in shutdown (EN pulled low). Both devices include a SET input, which when connected to ground, selects a preset output voltage of 5V (MAX5084) or 3.3V (MAX5085). Alternatively, the output voltage can be adjusted from 2.54V to 11V by connecting the SET pin to the regulator’s output through a resistive divider network.
