DESCRIPTION
Specifically
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
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
