... It offers 1.5% initial accuracy, extremely low dropout voltage (165mV at 100mA), and low ground current (typically full load). The MIC5253 provides a very low noise output, ideal for RF applications where a clean voltage source is required. A noise bypass pin is also available for further reduction of output noise ...

... This allows the output capacitor and load to dis- charge, de-energizing the load. November 2005 No-Load Stability The MIC5253 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 MIC5253 is designed to provide 100mA of continuous current in a very small package ...
