MIC5237 500 mA Low Dropout Regulator Features General Description Guaranteed 500 mA Output Over the Full The MIC5237 is a general-purpose low-dropout Operating Temperature Range regulator capable of 500 mA output current with better than 3% output voltage accuracy. Using Microchips Low 300 mV Typical Dropout Voltage at Full Load proprietary Super eta PNP process with a PNP pass Extremely Tight Load and Line Regulation element, these regulators feature less than 300 mV Current and Thermal Limiting dropout voltage and typically 8 mA ground current at Reversed-Battery Protection full load. TO-220 and TO-263 Packages Designed for applications that require moderate Low Temperature Coefficient current over a broad input voltage range, including No-Load Stability hand-held and battery-powered devices, the MIC5237 Low Noise Output is intended for applications that can tolerate moderate voltage drop at higher current. Applications Key features include low ground current to help prolong Portable and Laptop Computers battery life, reversed-battery protection, current Desktop Computer limiting, overtemperature shutdown, and thermally Battery Chargers efficient packaging. The MIC5237 is available in fixed output voltages only. SMPS Post-Regulator and DC/DC Modules Consumer and Personal Electronics For space-critical applications and improved performance, see the MIC5209 and MIC5219. For output current requirements up to 750 mA, see the MIC2937. Package Types MIC5237 MIC5237 3-Lead TO-220 (T) 3-Lead TO-263 (U) 3 OUT 3 OUT 2 GND 2 GND 1IN 1IN 2018 Microchip Technology Inc.
