Answer 1

IC Voltage Regulators

Question 2

is very important for the smooth functioning of many digital electronic devices.

Answer 2

Regulated Voltage

Question 3

These regulators provide a constant output voltage.

Answer 3

Fixed Voltage Regulators

Question 4

provides with constant positive output voltage.

Answer 4

Positive FIxed Voltage Regulator

Question 5

is same as the positive fixed voltage regulator in design, construction & operation.
The only difference is in the polarity of output voltages. These IC’s are designed to provide a negative output voltage.

Answer 5

Negative Fixed Voltage Regulator

Question 6

a kind of regulator whose regulated output voltage can be varied over a range.

Answer 6
