MIC5237
500mA Low-Dropout Regulator
Preliminary Information
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 regu-
lators 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 require-
ments up to 750mA, see the MIC2937.
