MIC5207

General Description

The MIC5207 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 (720µA at 100mA output). The MIC5207 offers better

than 3% initial accuracy.

Designed especially for hand-held, battery-powered devices,

the MIC5207 includes a CMOS or TTL compatible enable/

shutdown control input. When shutdown, power consump-

tion drops nearly to zero.

Key MIC5207 features include a reference bypass pin to

improve its already low-noise performance, reversed-battery

protection, current limiting, and overtemperature shutdown.

The MIC5207 is available in fixed and adjustable output

voltage versions in a small SOT-23-5 package. Contact

Micrel for details.

For low-dropout regulators that are stable with ceramic

output capacitors, see the µ Cap MIC5245/6/7 family.
