MIC5205
150mA Low-Noise LDO Regulator
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 (600â§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 shut down, power
consumption 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,
reversed-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 µCap MIC5245/6/7 family.
