The Texas Instruments LP3985 is a low-dropout linear regulator providing a fixed 5.0V output at up to 150mA. Featuring a low 0.1V dropout and 150µA quiescent current, it is well-suited for battery-operated and industrial equipment. The SOT-23-5 package enables compact designs, while 50dB PSRR at 1kHz delivers clean power for sensitive electronics. Protection features include thermal shutdown and current limiting.
- Stable 5V Rail: Fixed 5.0V output with tight regulation ensures reliable operation of 5V logic and analog circuits.
- Low Dropout: 0.1V dropout at 150mA supports efficient power conversion from 5.1V inputs.
- Noise Suppression: 50dB PSRR at 1kHz minimizes supply noise for high-precision applications.
- Space-Saving: SOT-23-5 package reduces board footprint for compact product designs.
