MIC5237

500mA Low-Dropout Regulator

General Description

Features

The MIC5237 is a general-purpose low-dropout regulator

capable of 500mA 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 300mV dropout voltage and

typically 8mA ground current at full load.

• Guaranteed 500mA output over the full operating

temperature range

• Low 300mV typical dropout voltage at full load

• Extremely tight load and line regulation

• Current and thermal limiting

• Reversed-battery protection

• TO-220 and TO-263 packages

• Low temperature coefficient

• No-load stability

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.

• 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

packaging. The MIC5237 is available in fixed output

voltages only.

Applications

• Portable and laptop computers

• Desktop computer

• Battery chargers

• SMPS post-regulator/dc-to-dc modules

• Consumer and personal electronics

For space-critical applications and improved performance,

see the MIC5209 and MIC5219. For output current

requirements up to 750mA, see the MIC2937.
