UA78M08CDCYR

UA78M08CDCYR Description

The UA78M08CDCYR from Texas Instruments is a fixed-output linear voltage regulator designed to deliver a stable 8V output at up to 500mA of continuous current. With a wide input voltage range of up to 25V, this regulator is engineered for applications requiring reliable voltage regulation in demanding environments. Its low dropout voltage of 2V (max) @ 350mA ensures efficient operation even when the input voltage approaches the output level. The device operates across a temperature range of 0°C to 125°C, making it suitable for industrial and automotive applications. Packaged in a SOT-223-4 surface-mount form factor, it is optimized for space-constrained designs.
