3 cards from this section. Quick, good the night before a test.
What series of IC voltage regulators is used for positive voltage?
Think of the numbers; ones that start with 7 are likely the answer.
Why is it important to have a stable voltage supply in circuits?
What happens to sensitive electronics under variable conditions?
What do the 78XX and 79XX series of IC voltage regulators provide?
Remember the number designations for each series.
True or False: IC voltage regulators can only operate at a fixed input voltage.
What is their primary function?
Design a simple power supply circuit using a 7805 voltage regulator. What components would you need, and how would you connect them?
Think about the steps to convert AC to usable DC before regulation.
Explain the implications of not using a voltage regulator in a sensitive analog circuit.
Consider the importance of voltage stability for signal integrity.
