• Evaluate short circuit protection
• Test high current handling
• Assess the ability to balance voltage spikes

• Multimeter
• Oscilloscope
• Adjustable DC Power Supply
• Electronic Load (programmable)
• Surge Generator
• Connecting wires and probes
• Components for test conditions (such as resistors for creating specific loads)

1. Power Connections:
   • Connect the adjustable DC power supply to the input of the voltage regulator $U1:VI$.
   • Connect a load (e.g., a resistance or electronic load) to the output of the voltage regulator $U1:VO$.
2. Measurement Points:
   • Monitor the voltage at the input $U1:VI$ and output $U1:VO$ with the multimeter or oscilloscope.
   • Monitor the current through the input and output.

1. Objective: Verify that the circuit can handle a short circuit condition without damage.
2. Steps:
   • Ensure the circuit is powered on.
   • Briefly short the output $U1:VO$ to ground (GND) while monitoring with oscilloscope.
   • Observe the response of the voltage regulator, particularly for shutdown or current limiting behavior.
   • Remove the short and observe if the circuit returns to normal operation.
3. Expected Results: The voltage regulator should protect itself by either reducing the output current or shutting down and should resume normal operation once the short is removed.

1. Objective: Check the voltage regulator's ability to handle high current loads.
2. Steps:
   • Connect an electronic load to the output of the regulator set to a high current level within the specifications of the 7805 voltage regulator.
   • Gradually increment the load current while monitoring voltage and current.
   • Observe any voltage drop or thermal shutdown behavior.
3. Expected Results: The regulator should provide a stable output voltage up to its specified current limit. Beyond this, it should exhibit current limiting or thermal shutdown.

1. Objective: Test the regulator's capability to handle and balance voltage spikes/transients.
2. Steps:
   • Use a surge generator to apply voltage spikes to the input $U1:VI$.
   • Monitor the output $U1:VO$ with an oscilloscope to observe how the regulator handles the spikes.
   • Record the response time and any deviations in the output voltage.
3. Expected Results: The output voltage should remain stable despite the input voltage spikes, demonstrating the regulator’s ability to filter out high-frequency transients.

• Use data sheets to record all voltages, currents, and any observed behaviors for each type of test.
• Annotate any deviations or unexpected behavior, noting the test conditions under which they occurred.

• Compare the recorded data against the expected results.
• Identify any failure modes or areas where performance does not meet expectations.
• Provide recommendations based on test findings.
