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.
