The LP5900TL-2.85 is a fixed 2.85V LDO regulator offering 150mA output with an ultra-low 50µA quiescent current. Its 150mV dropout and 85dB PSRR at 100Hz make it excellent for battery-powered, noise-sensitive applications. The 1x1mm DSBGA package is among the smallest available.
- Ultra-Low Quiescent Current: 50µA extends battery life in standby modes.
- Excellent PSRR: 85dB at 100Hz for clean analog supplies.
- Minimal Footprint: 1x1mm DSBGA package for ultra-compact designs.
- Low Dropout: 150mV at 150mA maintains regulation near battery end-of-life.
Battery-Powered IoT Sensors
The 50µA quiescent current significantly extends battery life in always-on sensor nodes.
Portable Audio Players
85dB PSRR at 100Hz ensures clean power for audio DACs, minimizing background noise.
Wearable Health Trackers
The tiny 1x1mm DSBGA package fits comfortably in wristbands and patches.
