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 (600⎧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. Data sheets and support documentation can be found on Micrel’s web site at www.micrel.com.
