ONSEMI MC7805BTG Linear Voltage Regulator, 5V, 1A, TO-220-3

The ONSEMI MC7805BTG is a positive linear voltage regulator engineered as a monolithic integrated circuit, designed to deliver a stable 5V output from a wide input range. This fixed-voltage regulator is ideal for a variety of applications, including local and on-card regulation, ensuring reliable performance where consistent power is critical.

Featuring robust internal protection mechanisms, this device includes thermal shutdown, internal short-circuit current limiting, and safe-area compensation. These built-in safeguards protect both the regulator and the connected circuitry from damage due to overcurrent or overheating conditions. With adequate heat-sinking, the regulator can deliver an output current exceeding 1A, making it suitable for higher-power loads.

Although primarily designed as a fixed 5V regulator, the MC7805BTG can be configured with external components to achieve adjustable voltages and currents, offering design flexibility. The device is Pb-free, aligning with modern environmental standards. It is available with output voltage tolerances of 1.5%, 2%, and 4% to suit various precision needs.
