AEK-POW-LDOV02J Evaluation Board Features  

The STMicroelectronics AEK-POW-LDOV02J evaluation board is a valuable tool for evaluating the L99VR02J automotive linear voltage regulator. The L99VR02J is a high-performance, high-temperature linear voltage regulator that is the core component of the evaluation board. The board can be configured to output any of eight fixed voltages from 0.8V to 5V. This makes it useful for a wide range of applications requiring a specific output voltage.

The evaluation board has different protection and diagnostics functionalities.  These include enable pin, reset, watchdog, programmable short circuit output current (Ishort), advanced thermal warning with output overvoltage detection, and fast output discharge. The output voltage of the board can be selected using the jumpers on the board. 

The watchdog can be configured to reset the board if the output voltage goes out of range or is unused for a specified period. This helps to prevent the board from becoming unstable or damaged. The enable pin is used to turn off the board when it is not being used. This helps to save power and extend the life of the board. The reset pin can restart the board if it becomes unstable. This can be useful for troubleshooting problems with the board.

The evaluation board includes other components, such as a power supply, a load, and an oscilloscope. These components are used to test and evaluate the performance of the L99VR02J automotive linear voltage regulator. The board can operate in temperatures ranging from -40°C to 175°C. This makes it ideal for applications subject to extreme temperatures, such as automotive and industrial applications.
