IC for Regulator+Reset Monolithic IC MM1481

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. [Package]SOP-8D [Applications]1. CD-ROM drive2.
