Abstract:

Specifically designed for data storage applications, this device integrates two voltage regulators, each one able to supply 1A and it is assembled in SPAK and in a new 8-PIN surface mounting package named DFN 5x6mm at 8 pins. The first regulator block supplies 1.5V, 1.8V, 2.5V,2.8V, 3.0V, 3.3V depending on the chosen version. The second one may be fixed to the same values or adjustable from 1.25V to VI - VDROP that could power several kind of different micro-controllers. Both outputs are current limited and over temperature protected. It is worth underlining the very good thermal performance of the packages SPAK and DFN with only 2°C/W of Thermal Resistance Junction to Case. Applications are HARD DISK, CD/DVD-ROM, CD/DVD-R/RW, COMBO (DVD-ROM+CD-R/RW).
