Which of the following voltage regulator IC gives a variable positive voltage?(a) LM317(b) LM337(c) 7805(d) 7812 |
|
Answer» Correct choice is (a) LM317 For explanation: LM317 is a variable positive voltage regulator IC. It is capable of drawing current up to 1.5A and voltage range from 1.25V- 30V ideally. LM337 is a variable negative voltage regulator IC. 7805 and 7812 are fixed voltage regulator IC that give output voltage as 5V and 12V respectively. |
