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.

Note 3: Transient response is defined with a step change in load from 10mA to 500mA as the time from the load step until the output voltage
reaches it’s minimum value.
Note 4: Minimum load current is defined as the minimum current required at the output in order for the output voltage to maintain regulation.
Note 5: Guaranteed by design, not tested in production.
