Today, we're diving into the 79XX series of voltage regulators. Who can tell me what a voltage regulator does?
Is it used to maintain a constant voltage output?
Exactly! And the 79XX series specifically provides negative voltage outputs. Can anyone name a common output from this series?
The 7905, which gives -5 volts.
Correct! The 7905 is one of our most commonly used regulators. Remember, it's not just about providing voltage; it's about stability. Let's think of a mnemonic to remember the 79XX series. We can use 'Negative Nine' for 7905, and 'Negative Twelve' for 7912.
Now, let’s delve into the specifics. What are some applications where the 7905 and 7912 might be used?
They're typically found in power supply circuits, right?
Absolutely! They stabilize the voltage for various circuits like microcontrollers. Why do you think powering embedded systems requires these regulators?
Because they need a reliable negative voltage to ensure proper functionality?
Well said! Consistency is key in electronics. Let’s summarize: The 7905 outputs -5V and the 7912 outputs -12V, both crucial for stable circuit operation.
To power systems running low, 79s help - no need to blow!
Imagine a car with a stabilizing system; without it, the engine sputters. Just like the 79XX keeps the voltage stable, allowing our circuits to run smoothly.
Use 'Negative Voltage with 79XX' to remember the negative voltage function.
79XX - '79 for Negative, XX for stability!'
