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⎧A at 100mA output). The MIC5205

offers better than 1% initial accuracy.

Designed

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

prolonging battery life.

Key MIC5205 features include a reference bypass pin to

improve its already excellent low-noise performance,

reversed-battery

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

Data sheets and support documentation can be found on

Micrel’s web site at www.micrel.com.
