The LM1117 is a series of low dropout voltage regulators with a dropout of 1.2V at 800mA of load current. It has the same pin-out as National Semiconductor’s industry standard LM317. The LM1117 is available in an adjustable version, which can set th
This document describes the method for design of the motor driving circuit using DSP. Especially you can know from document about method of interface 3.3V and 5V circuits.
