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
devices, the MIC5207 includes a CMOS or TTL compatible
enable/shutdown control input. When in shutdown, power
consumption 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 µCap MIC5245/6/7 family.
