Description
The UA78L05ACDR is a fixed-output, low-dropout linear voltage regulator designed to provide a stable 5V output from a higher voltage input. It is part of the UA78Lxx series, manufactured by Texas Instruments. The device is suited for applications requiring a compact, efficient power supply solution, such as in battery-powered devices and embedded systems.
Key features include a typical output current of up to 100 mA and a dropout voltage around 1.7V at full load. It offers internal current limiting, thermal shutdown, and safe-area compensation to protect against overload conditions. The UA78L05ACDR is available in a small, surface-mount SOT-23-3 package, making it ideal for space-constrained applications.
It operates over a wide input voltage range, generally between 7V and 20V, although this can vary. The regulator provides excellent line and load regulation, ensuring consistent performance across varying conditions. Its ease of use, combined with reliability and efficient power conversion, makes the UA78L05ACDR a popular choice for electronics requiring a stable 5V output.
