IC for Regulator+Reset Monolithic IC MM1482

[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 2. High ripple rejection rate 80dB typ. 3. Internal thermal shutdown circuit. 4. Internal current-limiting circuit. 0.3V typ. (Io=60mA MM3023A) 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 drive2. Optical disc drivers[Pin Assignment]SOP-8D(TOP VIEW) 1 N.
