The 7809 Voltage Regulator IC is a reliable linear regulator that provides a constant 9V DC output from a higher voltage input (typically 11V to 35V). It’s ideal for powering 9V logic circuits, motors, analog devices, and sensor modules that require a stable voltage.
Commonly used in DIY electronics, Arduino-based systems, and custom power supplies, the 7809 helps protect your components from voltage fluctuations. It’s easy to use, affordable, and widely available in the Bangladesh electronics market.
