In addition to an input voltage range what are the important characteristics of a three-terminal regulator?
- A Output voltage and maximum output current
- B Maximum output voltage and minimum output current
- C Minimum output voltage and maximum output current
- D Output voltage and minimum output current
Correct answer: A — Output voltage and maximum output current. From the official ISED question bank, verified word for word.
Why
A three-terminal regulator is designed to hold a steady output voltage regardless of changes in the input, so knowing that fixed value is essential. The full explanation — and one for every question — is in Pro.
