MIC5209

500mA Low-Noise LDO Regulator

General Description

The MIC5209 is an efﬁcient linear voltage regulator with

very low dropout voltage, typically 10mV at light loads and

less than 500mV at full load, with better than 1% output

voltage accuracy

Designed especially for hand-held, battery-powered

devices, the MIC5209 features low ground current to help

prolong battery life. An enable/shutdown pin on SO-8 and

TO-263- 5 versions can further improve battery life with

near-zero shutdown current.

Key features include reversed-battery protection, current

limiting, overtemperature shutdown, ultra-low-noise

capability (SO-8 and TO-263-5 versions), and availability

in thermally-efﬁcient packaging. The MIC5209 is available

in adjustable or ﬁxed output voltages.
