MinebeaMitsumi MM3478 is a 500mA LDO with soft-start. The soft-start reduces the rush current by means of a CS capacitor at start-up. SOT89-5A package provides high heat dissipation and space saving.
MM3478 features :
- Soft-start
MM3478 Applications :
- Audio visual equipment
- Photographing / Imaging device
- Office equipment / Printer
- Home appliance equipment
