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
ßeta PNP
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
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.
