MAX5087 pdf datasheet(Linear R

The MAX5087 high-voltage linear regulator operates
from an input voltage of 6.5V to 45V and delivers up to
400mA of output current. The device consumes only
70¦ÌA of quiescent current with no load and 11¦ÌA in
shutdown. The device includes a SET input, that when
connected to ground, selects a preset output voltage of
3.3V (MAX5087A) or 5.0V (MAX5087B). 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 MAX5087 also provides
an open-drain, active-low microprocessor (¦ÌP) 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 MAX5087 operates over the automotive temperature
range of -40¡ãC to +125¡ãC and is available in a 16-
pin TQFN thermally enhanced package.
