MIC5237
500mA Low-Dropout Regulator
General Description
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
?eta 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 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.
For space-critical applications and improved performance,
see the MIC5209 and MIC5219. For output current
requirements up to 750mA, see the MIC2937.
