Very Low Quiescent Current Dual Voltage RegulatorVery Low Quiescent Current Dual Voltage Regulator Specifically designed for data storage
applications, this device integrates two voltage
Regulators each one able to supply 1A and it is
assembled 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 2C/W of
Thermal Resistance Junction to Case.
Applications are HARD DISK, CD/DVD-ROM, CD/
DVD-R/RW, COMBO (DVD-ROM+CD-R/RW). By STMicroelectronics
