UA78M12CKVURG3 Description

Short technical summary and product information.

The Texas Instruments UA78M12CKVURG3 is a fixed-voltage integrated-circuit linear voltage regulator designed for a wide range of applications. It delivers up to 500mA of output current with a stable 12V output voltage. The device features an input voltage range of 5.3V to 35V and includes built-in short-circuit current limiting and thermal protection.

 

This regulator is suitable for on-card regulation to eliminate noise and distribution problems. It does not require external components for stable operation across the load current range. The UA78M series is characterized for junction temperatures from -40°C to +125°C.

 

The UA78M12CKVURG3 is supplied in a TO-252-3 surface-mount package, also known as DPak. This package is suitable for applications requiring moderate power dissipation and ease of surface mounting.

 

Key electrical characteristics include a typical quiescent current of 4.5mA and a PSRR of 80dB at 120Hz. The device offers protection features such as over current, over temperature, and short circuit protection.
