Microchip | MIC5209-5.0YM

The MIC5209-5.0YM is an efficient linear voltage regulator with very low dropout voltage, typically 10 mV 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, over temperature 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.

Features:

• Meets Intel® Slot 1 and Slot 2 requirements
• Guaranteed 500 mA output over the full operating
• temperature range
• Low 500 mV 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

Applications:

• Pentium II Slot 1 and Slot 2 support circuits
• Laptop, notebook, and palmtop computers
• Cellular telephones
• Consumer and personal electronics
• SMPS post-regulator/dc-to-dc modules
• High-efficiency linear power supplies
