MITSUMI IC for Regulator+Reset Monolithic IC MM1482 IC for Regulator+Reset MM1482 June 23, 1999 Outline This IC, developed for use in CD-ROM drives, combines a 3V regulator adapted to low power consumption with a much-sought reset function (regulator input monitoring), with internal delay circuit, set to detect 4.2V. Features 1. Large output current 300mA max. 2. High ripple rejection rate 80dB 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. 7. Operating temperature range and ripple elimination rate are available separately for 3 ranks. Package SOP-8D Applications 1. CD-ROM drive 2.
