MinebeaMitsumi's linear regulators (LDOs) features products that take advantage of the strengths of both CMOS and bipolar processes : they support output currents from 100 mA to 1.5 A and offer additional functions such as soft start, reverse current protection and auto discharge, as well as output current detection, temperature sensor output and other special functions are available. 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
