ONSEMI MC7805ABD2TG Linear Voltage Regulator, Fixed 5V 1A, TO-263

The ONSEMI MC7805ABD2TG is a monolithic, positive, fixed-voltage linear regulator, designed to deliver a stable 5V output from a variable input voltage between 10V and 35V. This highly reliable integrated circuit is ideal for a wide range of applications, from local power supply regulation on printed circuit boards (PCBs) to more complex on-card regulation systems. Its robust internal design ensures stable operation and protection for your sensitive electronic components.

A key feature of this regulator is its comprehensive suite of built-in protection mechanisms. It employs internal current limiting, thermal shutdown, and safe-area compensation for the output transistor. This combination safeguards the device against overloads, short circuits, and excessive operating temperatures. With the provision of adequate heat-sinking, the regulator can reliably deliver output currents exceeding 1 ampere, making it suitable for powering a variety of digital and analogue circuits.
