MC7912BT Description

Short technical summary and product information.

The ON Semiconductor MC7912BT is a member of the MC7900 series of fixed output negative voltage regulators. Designed as a complement to the MC7800 series, this device offers a stable -12V output voltage and can deliver up to 1A of current. It features internal thermal overload protection and short-circuit current limiting, making it a robust choice for various applications.

 

The regulator requires no external components for basic operation and is suitable for use in systems requiring a negative voltage rail. The TO-220 package with through-hole mounting is standard for power applications, allowing for adequate heatsinking to achieve maximum output current. The operating temperature range is -40°C to 125°C.

 

Key electrical characteristics include a maximum input voltage of -35V, a typical voltage dropout of 1.3V at 1A, and a PSRR of 61dB at 120Hz. The output configuration is fixed and negative, with a nominal output voltage of -12V.
