MIC5237

500mA Low-Dropout Regulator

General Description

Features

The MIC5237 is a general-purpose low-dropout regulator

•

Guaranteed 500mA output over the full operating

capable of 500mA output current with better than 3%

temperature range

output voltage accuracy. Using Micrel’s proprietary Super

•

Low 300mV typical dropout voltage at full load

ßeta PNP

process with a PNP pass element, these

•

Extremely tight load and line regulation

regulators feature less than 300mV dropout voltage and

•

Current and thermal limiting

typically 8mA ground current at full load.

•

Reversed-battery protection

Designed for applications that require moderate current

•

TO-220 and TO-263 packages

over a broad input voltage range, including hand-held and

battery-powered devices, the MIC5237 is intended for

•

Low temperature coefficient

applications that can tolerate moderate voltage drop at

•

No-load stability

higher current.

•

Low-noise output

Key features include low ground current to help prolong

battery life, reversed-battery protection, current limiting,

over-temperature shutdown, and thermally efficient

Applications

packaging. The MIC5237 is available in fixed output
