Composite regulator with ON/OFF
Monolithic IC MM1516
Outline
This IC was developed as a compound power supply and is composed of 3 positive voltage regulator
circuits. Regulator output voltage is fixed, and A ranks are set at 2.5V typ. 2.8V typ. and 3.0V typ. Switch
pins are provided to control each output. This IC is ideal for use in cellular telephones and the like.
