The 9V Voltage Regulator IC is a standard three-terminal positive linear voltage regulator engineered to convert higher unregulated DC input voltages (typically 11.5V to 35V DC) into a stable, noise-free 9V DC output. Housed in the heavy-duty TO-220 package, this IC can deliver up to 1.5A of continuous output current when paired with an adequate heatsink.
Equipped with built-in thermal overload protection, internal short-circuit current limiting, and output transistor safe-area protection, the L7809CV guards your circuits against electrical shorts and overheating. Its high ripple rejection capability makes it ideal for cleaning up noisy power rails and stepping down multi-cell battery packs or unregulated DC adapters.
The L7809CV is commonly used to power 9V audio effects pedals, sensors, relays, microcontrollers, and wireless modules. Featuring standard through-hole pins with 2.54mm pitch, it connects effortlessly into breadboards, stripboards, perfboards, and custom printed circuit boards (PCBs), making it fully compatible with Arduino, ESP32, Raspberry Pi, PIC, AVR, and general DIY electronics projects.
