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.
