... A guaranteed maximum dropout voltage of 500mV over all operating conditions allows the MIC39500 to provide 2.5V from a supply as low as 3V. The MIC39500 also has fast transient response, for heavy switching applications. The device requires only output capacitance to maintain ...

... A Transient Response The MIC39500/1 has excellent transient response to varia- tions in input voltage and load current. The device has been designed to respond quickly to load current variations and input voltage variations. Large output capacitors are not required to obtain this performance. A standard 47 F output capacitor, preferably tantalum, is all that is required ...

... A typical NPN regulator does not have the headroom to do this conversion. Minimum Load Current The MIC39500/1 regulator is specified between finite loads. If the output current is too small, leakage currents dominate and the output voltage rises. A 10mA minimum load current is necessary for proper regulation. ...
