Microchip | MIC5237-5.0YU

The MIC5237-5.0YU is a general-purpose low-dropout regulator capable of 500 mA output current with better than 3% output voltage accuracy. Using Micrel’s 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, over temperature shutdown, and thermally efficient packaging. The MIC5237 is available in fixed output voltages only.
