Unformatted text preview: V L = 1.1 V Creating a shortcircuit 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 1520mΩ. the output resistance shown on the datasheet was 15mΩ 2. With R sc =47Ω, calculate the theoretical shortcircuit 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...
