The LP3985ITL-285 from National Semiconductor is an ultra-small, fixed 2.85V LDO regulator designed for space-constrained portable electronics. It delivers up to 150mA with an exceptionally low dropout voltage of just 0.1V at full load. The 5-DSBGA package and low 150µA quiescent current make it an excellent choice for battery-powered and miniaturized applications.
- Ultra-Miniature Size: 5-DSBGA package (1.41x1.08mm) is among the smallest available, ideal for micro-electronics.
- Lowest Dropout: 0.1V dropout at 150mA maximizes efficiency and extends battery life.
- Low Quiescent Current: 150µA quiescent current minimizes standby power consumption.
- Precision Output: Fixed 2.85V output is well-suited for specific RF and analog ICs.
Ultra-Compact Wearables
The tiny 5-DSBGA package (1.41x1.08mm) is ideal for smartwatches, fitness bands, and medical patches where board space is extremely limited.
RF and Analog Front-Ends
The 2.85V output is often used for RF circuits and analog front-ends. The low dropout of 0.1V ensures stable operation from a 3.0V battery.
Battery-Powered Portable Devices
With 150µA quiescent current and low dropout, it maximizes battery life in portable devices like MP3 players and digital cameras.
Precision Sensor Power
Provides a clean, stable 2.85V supply for MEMS sensors, gyroscopes, and accelerometers, improving measurement accuracy.
Mobile Phone Accessories
Suitable for powering noise-sensitive circuits in smartphone accessories, such as external DACs and camera modules.
