MIC5209-1.8YM

MICREL SEMICONDUCTOR  MIC5209-1.8YM  固定稳压器, LDO, 2.5V至16V, 350mV压降, 1.8V输出, 500mA输出, SOIC-8

General Description

The MIC5209 is an effi cient 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 effi cient packaging. The MIC5209 is available in adjustable or fi xed output voltages.
