MIC5209
500mA Low-Noise LDO Regulator
General Description
The MIC5209 is an ef? 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
ef? cient packaging. The MIC5209 is available in adjustable
or ? xed output voltages.
Features
? Meets Intel ? Slot 1 and Slot 2 requirements
? Guaranteed 500mA output over the full operating
temperature range
? Low 500mV maximum dropout voltage at full load
? Extremely tight load and line regulation
? Thermally-ef? cient surface-mount package
? Low temperature coef? cient
? Current and thermal limiting
? Reversed-battery protection
? No-load stability
? 1% output accuracy
? Ultra-low-noise capability in SO-8 and TO-263-5
? Ultra-small 3mm x 3mm MLF? package
Applications
For space-critical applications where peak currents do not
exceed 500mA, see the MIC5219.
