The second one may be fixed to the same values or adjustable from 1.25V to VI www.DataSheet4U.com DESCRIPTION VDROP that could power several kind of different Specifically designed for data storage micro-controllers. Both outputs are current limited applications, this device integrates two voltage and over temperature protected. It is worth regulators, each one able to supply 1A and it is underlining the very good thermal performance of assembled in PPAK, in SPAK and in a new 8-PIN the packages SPAK and DFN with only 2°C/W of surface mounting package named DFN 5x6mm at Thermal Resistance Junction to Case. 8 pins. The first regulator block supplies 1.5V, Applications are HARD DISK, CD/DVD-ROM, CD/ 1.8V, 2.5V, 2.8V, 3.0V, 3.3V depending on the DVD-R/RW, COMBO (DVD-ROM+CD-R/RW).
