... It offers high precision, ultra-low dropout (500mV overtemperature), and low ground current. The MIC37139 operates from an input of 2.25V to 6.0V designed for a wide variety of applications including digital circuits requiring low-voltage at high currents (i.e., PLDs, DSPs, microcontrollers, etc.). It is available in a fixed output voltage of 1 ...

... Refer to “Application Note 9” for further details and examples on thermal design and heat sink applications. Output Capacitor The MIC37139 requires an output capacitor for stable operation µCap LDO, the MIC37139 can operate with ceramic output capacitors as long as the amount of capacitance is 47µF or greater. For values of output ® ...

... This gives the PNP-based regulators a distinct advantage over older, regulators. Minimum Load Current The MIC37139 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. 9 MIC37139 NPN-based ...
