EVAALVUAAILTAIOBNLEKIT _{45V, 250mA, Low-Quiescent-Current}
Linear Regulator with Adjustable Reset Delay
General Description
The MAX5086 high-voltage linear regulator operates
from a 6.5V to 45V input voltage and delivers up to a
250mA output current. The device consumes only 70µA
of quiescent current with no load and 13µA in shut-
down. The device includes a SET input, that when con-
nected to ground, selects a preset output voltage of
3.3V (MAX5086A) or 5.0V (MAX5086B). Alternatively,
the output voltage can be adjusted from 2.5V to 11V by
simply connecting SET to the regulator’s output through
a resistive divider network. The MAX5086 also provides
an open-drain, active-low microprocessor reset output
that asserts when the regulator output drops below the
preset output voltage threshold. An external capacitor
programs the reset timeout period. Other features
include an enable input, thermal shutdown, and short-
circuit protection.
The MAX5086 operates over the automotive tempera-
ture range of -40°C to +125°C and is available in a
16-pin TQFN thermally enhanced package.
