Unformatted text preview: V L = 1.1 V Creating a short-circuit and changing the 10kΩ potentiometer for a 1kΩ V L = 3.3 V Questions 1. Using the values in Table 1 and 2, determine the output resistance and the line regulator of the 7805. Use the manufacture’s specifications to compute specified output resistance. Compare them. Calculated from 15-20mΩ. the output resistance shown on the datasheet was 15mΩ 2. With R sc =47Ω, calculate the theoretical short-circuit current for the circuit in Figure 3. Compare the theoretical values measured in step 6. Calculated=0.01489A Measured=0.014A 3. Repeat question 2 for the circuit in Figure 3 with R sc =22Ω. Calculated=0.0318A Measured=0.029A 4. Compare the maximum load current(R sc =0Ω) measured in procedure step step 8 with the maximum load current specified by the manufacturer. Maximum=0.189A Maximum fro datasheet=1A...
