General Description
The MIC5206 is an efficient linear voltage regulator with
very low dropout voltage (typically 17mV at light loads and
165mV at 150mA), and very low ground current (600µA at
100mA output), with better than 1% initial accuracy. It has
a logic compatible enable/shutdown control input and an
internal undervoltage monitor.
Designed
devices, the MIC5206 can be switched by a CMOS or TTL
compatible
consumption drops nearly to zero. Dropout ground current
is minimized to prolong battery life.
Key features include an undervoltage monitor with an error
flag output, a reference bypass pin to improve its already
low-noise performance (8-pin versions only), reversed-
battery protection, current limiting, and overtemperature
shutdown.
The MIC5206 is available in several fixed voltages in a tiny
SOT-23-5 package. It features a pinout, similar to the
LP2980, but has significantly better performance. Fixed
and adjustable output voltage versions, featuring the
reference bypass option, are available in the 8-pin Micrel
Mini 8™ 8-pin MSOP (micro small-outline package).
For low-dropout regulators that are stable with ceramic
output capacitors, see the µCap MIC5245/6/7 family.

... See Figure 2. C reduces the regulator phase margin; when using C output capacitors of 2.2µF or greater are generally required to maintain stability. The start-up speed of the MIC5206 is inversely proportional to the size of the reference bypass capacitor. Applications requiring a slow ramp-up of output voltage should consider larger values of C ...
