DESCRIPTION Specifically designed for data storage applications, this device integrates two voltage regulators, each one able to supply 1A. It is assembled in PPAK and in a new surface mounting package named SPAK (PowerFlex) at 5 pins. The first regulator block supply 3.3V to power the Read Channel and Memory Chips requiring this voltage. The second one is an Adjustable output voltage from 1.25V to 3.0V that
could power several kind of different micro-controllers. Both outputs are current limited and overtemperature protected. The very good thermal performances of the package SPAK with only 2°C/W of Thermal Resistance Junction to Case is important to underline.
