65V, 200mA, Low-Quiescent-Current Linear Regulators in TDFN

Maxim Integrated

65V, 200mA, Low-Quiescent-Current

Linear Regulators in TDFN

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 out-

put 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 imped-

ance. 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 avail-

able in a space-saving 3mm x 3mm thermally

enhanced 6-pin TDFN package.
