Evaluation Boards - Linear Voltage Regulators

The TPS7A8901EVM-853 is an evaluation board that is designed to allow users to evaluate the performance of linear voltage regulators. The board is designed to use the TPS7A8901, a low noise, low dropout, adjustable, linear voltage regulator. The board features adjustable output voltage and is able to deliver up to 200mA of current. The board also contains a boost converter for powering the regulator.

The TPS7A8901EVM-853 board has many features that make it a useful tool for evaluating the performance of linear voltage regulators. First, the board is designed to support adjustable output voltage from 0.8V to 5.5V. This allows users to test the performance of different regulators under different conditions. The board also has two jumpers that control the output voltage of the regulator. By setting the jumpers, the user can quickly adjust the output voltage of the regulator without having to manually adjust the voltage setting on the regulator.

The board also contains a boost converter to power the regulator. The boost converter is designed to take a 5V input voltage and provide an output voltage of up to 9V. The board also contains an on-board 3.3V regulator to provide the necessary voltage for the regulator. Additionally, the board features a variable resistance trim terminal to allow the user to adjust the output voltage of the regulator.

The TPS7A8901EVM-853 board can be used in many different applications. It is ideal for use as an adjustable power supply, or for providing the necessary voltage for powering devices such as processors, FPGAs, and microcontrollers. Additionally, the board is suitable for use in multiple applications such as automotive, instrumentation, industrial control, and medical applications.

In order to properly evaluate the performance of the TPS7A8901EVM-853 board, it is important to understand the working principle of a linear voltage regulator. A linear voltage regulator is a type of voltage regulator which maintains a constant output voltage by regulating the input voltage. The input voltage is compared to the reference voltage and if the input voltage is higher than the reference voltage, the regulator will reduce the output voltage to maintain the reference voltage.

To ensure the best performance from the TPS7A8901EVM-853 board, it is important to choose the correct input voltage and to set the output voltage correctly. Additionally, it is important to understand the impact of loading on the regulator. Loading a regulator too heavily can affect the output voltage and cause it to become unstable. By ensuring that the regulator is not overloaded, users can be sure to get the best performance from the board.

In summary, the TPS7A8901EVM-853 board is an excellent tool for evaluating the performance of a linear voltage regulator. The board features adjustable output voltage, a boost converter, and a variable resistance trim terminal. Additionally, it is important to understand the working principle of a linear voltage regulator in order to get the best performance from the board.
