Ultra-Low-Noise 5V Regulator
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 shut-
down current.
Key features include reversed-battery protection, current
limiting, overtemperature shutdown, ultra-low-noise capabil-
ity (SO-8 and TO-263-5 versions), and availability in ther-
mally efficient packaging. The MIC5209 is available in adjust-
able or fixed output voltages.
For space-critical applications where peak currents do not
exceed 500mA, see the MIC5219.
