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
