Linear Voltage Regulator L78M09CV (L7809CV) TO-220 is commonly used in electronic circuits to regulate the voltage and ensure a consistent power supply to other components.
The L78M09CV is a fixed output, three-terminal precision positive voltage regulator in 3 3-pin TO-220 package. This regulator can provide local on-card regulation by eliminating distribution problems associated with single-point regulation. The L78M09CV fixed voltage regulator is designed with thermal overload protection that shuts down the circuit when subjected to an excessive power overload condition, internal short circuit protection that limits the maximum current the circuit will pass, and output transistor safe area compensation that reduces the output short circuit as the voltage across the pass transistor is increased. If adequate heat sinking is provided then this positive voltage regulator can deliver over 0.5A output current.
The L78M09CV (also known as L7809CV) is a linear voltage regulator in a TO-220 package. This regulator is designed to provide a stable output voltage of 9 volts when powered by an input voltage within its specified range.
This pack includes 3 ICs of the L78M09CV, which allows for multiple applications or spares. Linear voltage regulators like the L78M09CV are widely used in various electronic devices and projects, providing a reliable solution for voltage regulation needs.
Here are some additional features and characteristics of the L78M09CV linear voltage regulator:
High Accuracy: The L78M09CV provides precise voltage regulation with low output voltage tolerance, ensuring consistent performance across a range of operating conditions.
Low Dropout Voltage: It has a low dropout voltage, meaning it can regulate the output voltage even when the input voltage is only slightly higher than the desired output voltage.
Overcurrent Protection: Incorporates overcurrent protection to safeguard against excessive current draw, protecting both the regulator and the connected circuitry from damage.
Thermal Shutdown: Includes thermal shutdown protection to prevent overheating, automatically shutting down the regulator if the temperature exceeds safe limits, and then resuming operation once the temperature decreases.
Short-Circuit Protection: Designed with short-circuit protection to prevent damage in the event of a short circuit on the output, helping to safeguard the regulator and connected components.
