... As a µCap regulator, the MIC5238 operates with a 2.2µF ceramic capacitor on the output, offering a smaller overall solution. It also incorporates a logic-level enable pin that allows the MIC5238 to be put into a zero off-current mode when disabled. The MIC5238 is fully protected with current limit and thermal shutdown ...

... X7R ceramic capacitor to ensure the same minimum capacitance over the equivalent operating temperature range. No-Load Stability The MIC5238 will remain stable and in regulation with no load unlike many other voltage regulators. This is especially important in CMOS RAM keep-alive applications. Thermal Considerations The MIC5238 is designed to provide 150mA of continuous current in a very small package ...
