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. 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-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 Micrel, Inc. • 1849 Fortune Drive • San Jose, CA 95131 • USA • tel + 1 (408) 944-0800 • fax + 1 (408) 944-0970 • http://www.micrel.com Ordering Information Part Number Voltage Junct.
