MICROCHIP MIC5237-3.3YU

The MIC5237 is a general-purpose low-dropout regulator capable of 500 mA output current with better than 3% output voltage accuracy. Using proprietary Super ßeta PNP process with a PNP pass element, these regulators feature less than 300 mV dropout voltage and typically 8 mA ground current at full load. Designed for applications that require moderate current over a broad input voltage range, including hand-held and battery-powered devices, the MIC5237 is intended for applications that can tolerate moderate voltage drop at higher current. Key features include low ground current to help prolong battery life, reversed-battery protection, current limiting, overtemperature shutdown, and thermally efficient packaging. The MIC5237 is available in fixed output voltages only.
