Regulator+Reset IC MM1478
Regulator+Reset IC
Monolithic IC MM1478
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
3. Internal thermal shutdown circuit.
4. Internal current-limiting circuit.
5. Adjustment-free reset detection voltage
6. Easy to set delay time from voltage detection to reset release.
300mA max.
80dB typ.
4.2V typ.
