4/4/2024 0 Comments L7812 datasheet![]() The device is available in a hermetically sealed TO-3 metal package, and facilitates easy fitting of an heatsink for better efficiency and working of the device. The above feature ensures safe operations of the connected electronics and also avoids the inclusion of external safety circuits reducing the cost and the component count of the over all configuration. The situation also protects the IC from getting damaged. In an event of a short circuit or over load across its output terminals, the device instantly shuts down the supply of power across its output leads, thus inhibiting any possibility of electrical hazards. The IC is internally fully protected a against short circuits or over loads at its output which makes it highly rugged and versatile. The 78H12A is a three terminal linear, positive fixed voltage regulator IC rated for continuously delivering around 5 amps of current with typical fixed 12 volts at its output. The main technical specifications or datasheet of this IC 78H12A may be studied with the following explanation: However the above device is capable of handling at the most 1 Amp of current which may be not sufficient for many standard applications.įor circuit applications which require currents as high as 5 amps, a higher rated alternative may be selected in the form of the IC 78H12A which is quite similar to its younger brother 7812 but is capable of handling up to 5 amps of current. We are familiar with the popular 78XX ICs such as the 7812 IC which can produce 12V fixed voltage at its output with input supplies anywhere from 15V to 24V. ![]()
