[Outline]
This IC is a regulator (2 circuits) + reset IC developed for optical disc drives such as DVD-ROM drives.
Regulator output voltage and reset detection voltage are fixed, while regulator output voltage and reset detection voltage are programmable ranging from 1.5V to 5.0V, and 2.7V to 5.0V respectively upon request.
