What can a 7812ct datasheet be used for?
by Diode 7812CT Datasheet PDF learn more. This is a kind of semiconductor. These linear voltage regulators are monolithic integrated circuits designed as fixed-voltage regulators for a wide variety of applications including local, on-card regulation.
What is the output voltage of a 7812?
The 7812 is a commonly used linear regulator. Input voltage can range from 14 – 35VDC and it outputs a fixed 12V at over 1A of current and up to 2.2A of surge current. For basic operation, no external components are required. Just hook up the input voltage and ground and you have 5V available on the output.
How is the power dissipation of a 7812 device calculated?
The power dissipation of the 7812 device is easily calculated as Power Dissipation = (Vin – Vout) * Iout. If the 7812 input is 15V and it is providing 1A of current, then Power Dissipation = (15V – 12V) * 1A = 3W. The 7812 TO-220 package will need to dissipate 3W of power.
