... It offers high precision, ultra-low dropout (500mV over temperature), and low ground current. The MIC37150/51/52 operates from an input of 2.25V to 6.0V designed to drive digital circuits requiring low voltage at high currents (i.e., PLDs, DSPs, microcontrollers, etc.). It is available in fixed and adjustable output voltages. ...

... NPN-based regulators are already operating in dropout, with typical dropout requirements of 1.2V or greater. To convert down to 2.5V without operating in dropout, NPN-based regulators require an input voltage of 3.7V at the very least. The MIC37150/51/52 regulator will provide excellent performance with an input as low as 3. “Application Note 9” ...

... This gives the PNP-based regulators a distinct advantage over older, NPN-based linear regulators. Minimum Load Current The MIC37150/51/52 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 operation. ...
