... Tantalum or ceramic capacitors are recommended for operation below –25C . No-Load Stability The MIC5203 will remain stable and in regulation with no load (other than the internal voltage divider) unlike many other voltage regulators. This is especially important in CMOS RAM keep-alive applications. ...
