DESCRIPTION
   The MP20049 is an ultra-low noise, low-dropout, high PSRR linear regulator. Fixed output voltage options are available between 1.2V to 4.5V with 1% accuracy while operating from a +2.3V to +6V input. It is designed to deliver up to 150mA of load current. Dropout voltage is only 60mV at full load.
