Hi guys. Im having a bit of trouble with my assignment on electronics. Could you guys help me with how the circuit should look like and what values the components should be.
A customer has requested a recommendation for the lowest possible cost power supply circuit with the following specification, and in the format of a written report:
1. Vin = 20 Vdc
2. Vout = 3.3 Vdc at 300 mA
3. An LED to indicate that the power supply is supplying 3.3 V to the load
(We have to use a zener diode as a regulator).
