MM1923J

MITSUMI Regulator IC with the Soft-Start MM192x Series Regulator IC with the Soft-Start Monolithic IC MM192x Series Outline This IC is 1A regulator IC with soft-start. When Cs pin is connected with a capacitor, the output voltage is started up slowly. This IC can reduce a rush current by the soft-start. Therefore a transformer in a power supply for this IC can be small, and it is possible to reduce a total cost in the power supply system. And this IC can be turned off by Cont pin. Package TO-252-5 or HSOP-8 were used for this device. Features 1. 2. 3. 4. 5. 6.
