Description

The IRU1237SC voltage regulator solution contains three integrated, fixed, linear voltage regulators in one 7-pin surface mount package. The first is a 2.6V regulator to power the read channel and integrated controller/mP. The second is a 3.3V regulator to power the controller I/O 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. 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 each be capable of 1.2A continuous for a 5.25V input. The 8V regulator shall be capable of 0.2A continuous for a 13.2V input.
