Negative voltage: An output using 3 terminal regulator positive input
Latest Updated:12/01/2011
Question:
For a 3-terminal regulator, can a negative voltage be output when a positive voltage is input?
Answer:
Yes, it can.
The output that can be obtained differs depending on the circuit configuration, as follows.
- Output voltage lower than input voltage (step down)
- Output voltage higher than input voltage (step up)
- Output voltage that has reverse polarity to input voltage (inverted)
