MIC5205
General Description
The MIC5205 is an efficient linear voltage regulator with ultra-
low-noise output, very low dropout voltage (typically 17mV at
light loads and 165mV at 150mA), and very low ground
current (600
μ
A at 100mA output). The MIC5205 offers better
than 1% initial accuracy.
Designed especially for hand-held, battery-powered devices,
the MIC5205 includes a CMOS or TTL compatible enable/
shutdown control input. When shutdown, power consump-
tion drops nearly to zero. Regulator ground current increases
only slightly in dropout, further prolonging battery life.
Key MIC5205 features include a reference bypass pin to
improve its already excellent low-noise performance, re-
versed-battery protection, current limiting, and
overtemperature shutdown.
The MIC5205 is available in fixed and adjustable output
voltage versions in a small SOT-23-5 package.
For low-dropout regulators that are stable with ceramic
output capacitors, see the
μ
Cap MIC5245/6/7 family.
