Outline
This IC is a 300mA-output low-saturation type Dual regulator developed as a combined power supply for cell-phones. The output voltages of the regulator can be fixed to desired voltages in a 1.2 V to 5.0 V range. The device is further provided with a switching terminal for each output, making it an IC especially suitable for cell-phones.
