DESCRIPTION
Specifically
designed
for
data
storage
applications, this device integrates two voltage
regulators, each one able to supply 1A and it is
assembled in PPAK, 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).
