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.
