... Composite Regulator Monolithic IC MM1448 Outline This IC was developed as a composite power supply for the RF section of mobile telephones composed of three normal voltage regulator circuits, of which the output of one circuit is divided for two switching circuits. The regulator output voltage is fixed, and each can be set between 2.0V and 5.0V according to the customer's needs ...
