General Description

The MIC5237 is a general-purpose low-dropout

regulator capable of 500 mA output current with better

than 3% output voltage accuracy. Using Microchip’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, overtemperature 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 750 mA, see the

MIC2937.
