Outline
This IC was developed as a composite power supply for the RF section of mobile telephones. It is 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 customers needs. Output noise voltage noise reduction is made possible by using the noise reduction pin. Also, switch pins are provided to control each output, making this an ideal IC for use in portable equipment.
