Using the Internal OPAMP as Regulated Power Supply for MVIO
This application note describes how to use the Analog Signal Conditioning (OPAMP) as a regulated power supply for a second voltage domain. This removes the need for a second power supply. The regulated power supply features are showcased by acting as the second power supply for the Multi-Voltage I/O (MVIO).
