LM7805 LM7809 LM7812 DC/AC Three Terminal Voltage Regulator Power Supply Module 5V 9V 12V Output Max 1.2A

L7812 LM7812 three terminal regulator module 12V power supply rectifying and smoothing a power converter module

• 3A bridge rectifier (AC, DC can enter)

• 2 * 35V 220UF high-voltage capacitor (filtering do buffer)

• high-quality radiators (supporting fins to enhance heat dissipation)

• 1.5A large current chip (usually with different network products is less and 1.2A, jerry)

This board uses a full-wave bridge rectifier, AC, DC can be input, regardless of positive and negative input. Filtering using two large-capacity electrolytic capacitor 35V 220UF buffer do filtering, smoothing allows the output current is stable. L7812 is equipped with fins, and 3A of the rectifier bridge, to meet the high-current output.
