Equivalent Circuit Diagram
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.
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.
7. Operating temperature range and ripple elimination rate are available separately for 3 ranks.
