... and a few more tests. Please have a look and tell me what you think.
1. Vout= 4.8V, Iout=3A, Rl=12 ohm: 0015, 0016
2. Vout=13V, Iout=3A, Rl=4.7 ohm: 0010
3. Vout=13.2V, Iout=1.5A, Rl=10 ohm: 0021
4. Vout= 14.79V, Iout=1.5A, Rl=10 ohm: 0022
5. Vout=3.23V, Iout=almost zero A, Rl=27R: 0029
6. Vout=3.23V, Iout=almost zero A, Rl=10R: 0032, 0033 (0033 is with BW limit enabled for CH1)
The yellow trace shows the output of the psu and the blue trace shows the output of the NE555.
