DESCRIPTION This unit contains three voltage regulators, all fixed output voltages, in a 7-pin surface mount package. The first is a 2.6 V regulated power supply integrated controller/microprocessor. The second one is a 3.3V regulated power supply for the read channel chip, and the memory chip needs 3.3V for the last 8V regulated power supply for the preamp chip. The bandgap reference, the 8V ground, is tied to a common pin with the substrate, while the 2.6V and 3.3V grounds are tied to a separate ground pin.This grounding scheme can improve noise isolation between the 8V regulator and the 2.6V and 3.3V regulators.The 2.6V and 3.3V regulators should be 1.0A and 1.2A respectively. The 8V regulator should be capable of 200mA.
