UA78M12CKCS Description

Short technical summary and product information.

The Texas Instruments UA78M12CKCS is a positive, fixed-voltage linear regulator designed for a wide range of applications. It delivers up to 500mA of output current and operates with an input voltage range of 5.3V to 35V. This device is characterized for a junction temperature range of -40°C to +125°C.

 

Key features include built-in short-circuit current limiting and thermal protection, which help protect the device from overload conditions. The UA78M12CKCS is stable without external components, simplifying circuit design. It is supplied in a TO-220-3 package suitable for through-hole mounting.

 

This regulator is well-suited for on-card regulation to eliminate noise and distribution problems. It can also be used with power-pass elements to create high-current voltage regulators. Applications include on-board charging, residential lighting, and battery backup units.
