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. The MAX5084/MAX5085 also include an OUT_SENSE pin, which allows remote voltage sensing right at the load, thus eliminating the voltage drop caused by the line impedance. Both devices are short-circuit protected and include thermal shutdown.

The MAX5084/MAX5085 operate over the -40°C to +125°C automotive temperature range and are available in a space-saving 3mm x 3mm thermally enhanced 6-pin TDFN package.
