The MIC5237 is a general purpose low-dropout regulator capable of 500mA output current with better than 3% output voltage accuracy. Using proprietary Superβeta PNP^® process with a PNP pass element, these regulators feature less than 300mV dropout voltage and typically 8mA ground current at full load.

Designed for applications that require moderate current over a broad input voltage range, including handheld 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, over-temperature shutdown, and thermally efficient packaging. The MIC5237 is available in fixed output voltages only.

For space-critical applications and improved performance, see the MIC5209 and MIC5219. For output current requirements up to 750mA, see the MIC2937.
