1.3 Description

for the I/Os and memory in the system.

The device includes eight general-purpose LDOs providing a wide range of voltage and current

capabilities. The LDOs are fully controllable by the I

2C interface. The use of the LDOs is flexible; they are

intended to be used as follows: Two LDOs are designated to power the PLL and video DAC supply rails

on the OMAP-based processors, four general-purpose auxiliary LDOs are available to provide power to

other devices in the system, and two LDOs are provided to power DDR memory supplies in applications

requiring these memories.
