2 cards from this section. Quick, good the night before a test.
What does the 'XX' in the 78XX series represent?
Think about the numbers that follow the 78.
Name one application of the 79XX series.
Consider where negative voltage is necessary.
What output voltage does the 7805 regulator provide?
Remember what the numbers indicate in the part numbers.
Is the 79XX series used for positive voltage regulation?
Think about the type of voltage each series manages.
Given a circuit needing a 12V power source for a microcontroller and -5V for an operational amplifier, how would you integrate both the 78XX and 79XX series? Sketch the circuit.
Think about how to connect both regulators from a common supply.
Discuss the failures that might occur if a device is supplied with voltage below its operational requirements due to an incorrectly chosen regulator.
Consider a device's operational range and the repercussions of underperformance.
