3V, 8V) 2.
6V GUARANTEED IOUT UP TO 1.
2A 3.
3V GUARANTEED IOUT UP TO 1.
0A 8V GUARANTEED IOUT UP TO 200mA THERMAL AND SHORT CIRCUIT PROTECTION GUARANTEED OPERATING TEMPERATURE RANGE (0°C to 125°C) SPAK-7L (PowerFlex™) DESCRIPTION This device contains three voltage regulators, all fixed output voltage, in one 7 pin surface mount package.
The first is a 2.
6 V regulator to power the integrated controller/µP.
The second is a 3.
3V regulator to power the read channel chip, and memory chips requiring 3.
3V The last is an 8V regulator to power the preamp chip.
The bandgap reference, the 8V ground, and the substrate are all tied to a common ground pin, while the 2.
6V and 3.
3V ground is tied to a separate ground pin.
