Simple Power Solution Using LDOs

ABSTRACT

This reference design helps those desiring to design-in the TMS320C6742, TMS320C6746,

TMS320C6748, and OMAP-L138. This design, employing sequenced power supplies, describes a system

with an input voltage of 3.3 V, and uses LDOs for a small, simple system.

Sequenced power supply architectures are becoming commonplace in high-performance microprocessor

and digital signal processor (DSP) systems. To save power and increase processing speeds, processor

cores have smaller geometry cells and require lower supply voltages than the system bus voltages. Power

management in these systems requires special attention. This application report addresses these topics

and suggests solutions for output voltage sequencing.
