circuitcomponents 7805 Positive Linear Voltage Regulator (Pack of 2 Ics) Electronic Components Electronic Hobby Kit

A LM7805 Voltage Regulator is a voltage regulator that outputs +5 volts, Pin 1 (Input Pin): The Input pin is the pin that accepts the incoming DC voltage, which the voltage regulator will eventually regulate down to 5 volts., Pin 2 (Ground): Ground pin establishes the ground for the regulator., Pin 3 (Output Pin): The Output pin is the regulated 5 volts DC. The 7805 series of the three-terminal positive regulator are available in the TO-220/D-PAK package and with several fixed output voltages, making them useful in a wide range of applications. Each type employs internal current limiting, thermal shut-down and safe operating area protection, making it essentially indestructible. If adequate heat sinking is provided, they can deliver over 1A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.
