) _DESCRIPTION
t(s ^{This device contains three voltage regulators, all}
c _{fixed output voltage, in one 7 pin surface mount}
u _{package. The first is a 2.6 V regulator to power the}
d _{integrated controller/µP. The second is a 3.3V}
ro regulator to power the read channel chip, and
P memory chips requiring 3.3V The last is an 8V
te ^{regulator to power the preamp chip. The bandgap}
reference, the 8V ground, and the substrate are all
le _{tied to a common ground pin, while the 2.6V and}
o _{3.3V ground is tied to a separate ground pin.This}
grounding scheme allows for improved noise
isolation between the 8V regulator and the 2.6V
and 3.3V regulators.The 2.6V and 3.3V regulators
shall be respectively capable of 1.0A and 1.2A.
The 8V regulator shall be capable of 200mA.
It is housed in the SPAK (PowerFlex™)
