MC7809BTG Description

Short technical summary and product information.

The MC7809BTG from On Semiconductor is a versatile positive voltage regulator designed for a wide range of applications requiring stable voltage regulation. This device provides a fixed 9V output voltage with a maximum output current capability of 1A. It is built with internal circuitry for current limiting, thermal shutdown, and safe-area compensation, enhancing its reliability and simplifying external component requirements.

 

The regulator operates with an input voltage range up to 35V and features a typical voltage dropout of 2V at 1A. Its operating temperature range is -40°C to 125°C, making it suitable for various environmental conditions. The TO-220-3 package with through-hole mounting is standard for many power applications.

 

Key electrical characteristics include a quiescent current of 8 mA and a Power Supply Rejection Ratio (PSRR) of 61dB at 120Hz. These features make the MC7809BTG a robust choice for local on-card regulation and other power management tasks where a reliable fixed voltage is needed.
