... For the worst-case situation of a 250mA load at 1.23V output (output shorted to feedback) a 5µF (or greater) capacitor should be used. The MIC2954 will remain in regulation with a minimum load of 1mA. When setting the output voltage of the MIC2954-07/-08 version with external resistors, the current through these resistors may be included as a portion of the minimum load. A 0.1µ ...
