Outline
This IC was developed for use in CD-ROM drives and other optical disc drives. It combines two 3V system regulator lines and reset (monitors regulator input) with a built-in 4.2V detection delay circuit that responds to market needs.

Features
1. Large output current 300mA max.
2. High ripple rejection rate regulator1: 80dB typ. regulator2: 60dB typ.
3. Internal thermal shutdown circuit.
4. Internal current-limiting circuit.
5. Adjustment-free reset detection voltage 4.2V typ.
6. Easy to set delay time from voltage detection to reset release.

Applications
1. CD-ROM drive
2. Optical disc drives
