... SOT-223 package. The MIC39101 and MIC39102 are fixed and adjustable regulators, respectively thermally en- hanced power 8-lead SOIC package. The MIC39100/1/2 is ideal for PC add-in cards that need to convert from standard 5V to 3.3V, 3.3V to 2.5V or 2.5V to 1.8V. A guaranteed maximum dropout voltage of 630mV over all operating conditions allows the MIC39100/1/2 to provide 2 ...

... PNP based regulators a distinct advantage over older, NPN based linear regulators. Minimum Load Current The MIC39100/1/2 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. ...
