Functionality and Working Principle

The TPS7A84EVM-753 EVM operates on the basic concept of a Linear Voltage Regulator (LVR), where a fixed output voltage is provided by controlling the current flow of a device using a resistor divider network. The device utilizes an on-resistor between the input and output pins to regulate the input voltage. This resistor size is determined by the output voltage and the load current. When the load current increases, the resistor size is increased to increase the voltage across the load and maintain the output voltage. When the load decreases, the resistor size is decreased to reduce the voltage across the load and maintain the output voltage.

The TPS7A84Q1 has an integrated feedback network which allows it to accurately regulate the output voltage currently. The feedback network is used to sense the output voltage and adjust the current going to the load to maintain the output voltage at a constant value. The device can also be used to provide adjustable output voltages, either through the use of external pins or via a software program.

In summary, the Texas Instruments TPS7A84EVM-753 is a versatile and highly reliable evaluation board designed for quickly and easily evaluating and verifying the performance of the TPS7A84Q1 Ultra-Low Dropout Voltage regulator. The evaluation module can be used for a wide variety of applications, ranging from consumer electronics and automotive systems to portable audio and video devices. Its integrated feedback network provides accurate output voltage control and the device features an on-resistor dropout voltage of 0.4V to 0.6V to minimize energy loss.
