7806 IC Fixed Positive 6V Voltage Regulator
The 7806 is a three-terminal positive voltage regulator that outputs a fixed 6V from a higher unregulated DC input. It is part of the popular 78xx series of linear regulators, known for their simplicity and reliability in DC power supply applications. Widely used in embedded electronics, robotics, and consumer devices where stable voltage is required.e. If adequate heat sinking is provided, they can deliver over 1A output current.
It supports input voltages from around 8V up to 25V and can supply output currents up to 1A. The device features internal mechanisms for current limiting, thermal overload protection, and safe operating area (SOA) control, which help prevent damage under fault conditions. This regulator delivers a clean, regulated 6V output, making it suitable for analog circuits, microcontrollers, sensors, and other low-voltage digital systems.
