7812 Datasheet – MC7812 – Voltage Regulator – Motorola

A voltage regulator is an electronic device that is used to maintain a constant voltage level, regardless of changes in load or input voltage. It does this by adjusting the output voltage so that it remains within a specified range.

This helps to ensure that the voltage supplied to a device remains within the acceptable range, even under varying conditions such as changes in temperature or load.

Part Number: 7812


Manufacturer: Motorola Inc

7812 is 12V, Voltage Regulator. These voltage regulators are monolithic integrated circuits designed as fixed–voltage regulators for a wide variety of applications including local, on–card regulation. These regulators employ internal current limiting, thermal shutdown, and safe–area compensation. With adequate heatsinking they can deliver output currents in excess of 1.0 A. Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents.



• Output Current in Excess of 1.0 A

• No External Components Required

• Internal Thermal Overload Protection

• Internal Short Circuit Current Limiting

• Output Transistor Safe–Area Compensation

• Output Voltage Offered in 2% and 4% Tolerance

• Available in Surface Mount D2PAK and Standard 3–Lead Transistor Packages

• Previous Commercial Temperature Range has been Extended to a Junction Temperature Range of –
40°C to +125°C
