MIC5209  
500mA Low-Noise LDO Regulator  
General Description  
Features  
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.  
• 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-efficient surface-mount package  
• Low temperature coefficient  
• 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  
Designedespeciallyforhand-held,battery-powereddevices,  
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,overtemperatureshutdown,ultra-low-noisecapability  
(SO-8 and TO-263-5 versions), and availability in thermally  
efficient packaging. The MIC5209 is available in adjustable  
or fixed output voltages.  
Applications  
• Pentium II Slot 1 and Slot 2 support circuits  
• Laptop, notebook, and palmtop computers  
• Cellular telephones  
For space-critical applications where peak currents do not  
exceed 500mA, see the MIC5219.  
• Consumer and personal electronics  
• SMPS post-regulator/dc-to-dc modules  
• High-efficiency linear power supplies
