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.

The 79XX Series are negative voltage regulators designed to provide stable output voltages.
Detailed Explanation
The 79XX Series is a collection of integrated circuits specifically designed to regulate negative voltage. Each regulator in this series outputs a specific negative voltage, such as -5V or -12V, making it essential for supplying a consistent voltage to circuits that require negative power. This ensures that sensitive components always receive the correct voltage, which prevents damage and optimizes performance.
Examples & Analogies
Think of the 79XX Series like a well-calibrated thermostat that maintains a set temperature in your home while itβs cold outside. Just as the thermostat keeps the temperature stable, the 79XX voltage regulators keep the voltage levels steady and reliable for electronic circuits.

Common outputs include 7905 and 7912.
Detailed Explanation
The 79XX Series consists of various models, with 7905 and 7912 being among the most common. The '79' signifies that these are negative voltage regulators, while the numbers '05' and '12' indicate the output voltages of -5V and -12V, respectively. This implies that these regulators can convert a higher input voltage to a stable negative output voltage suitable for specific components or applications in electronic devices.
Examples & Analogies
Imagine you have different water taps in your houseβone for cold water and another for hot water. The 7905 and 7912 are like those water taps, allowing you to draw the exact negative voltage you need for different parts of a circuit, just as you choose between cold or hot water for various tasks.
