The Texas Instruments LP5900SDX-2.8 is a fixed-output, low-dropout linear regulator delivering 150mA with a precise 2.8V output. Its ultra-low 50μA quiescent current and 150mV dropout voltage make it exceptionally efficient for battery-powered applications. The device offers superior power supply rejection (85dB at 100Hz), ensuring clean power for sensitive electronics. Housed in a compact 6-WSON package, it is ideal for space-constrained designs requiring reliable, low-noise performance.
- Extended Battery Life: Ultra-low 50μA quiescent current minimizes standby power draw, ideal for portable devices.
- Clean Power Delivery: High PSRR (85dB at 100Hz) filters out supply noise, protecting sensitive analog and RF circuits.
- High Efficiency at Low Dropout: 150mV dropout at 150mA allows operation close to the battery's discharge threshold, maximizing usable energy.
- Compact Footprint: The 6-WSON (2.2x2.5) package saves board space for miniaturized designs.
Battery-Powered IoT Sensors
The LP5900's low 50μA quiescent current and 150mV dropout at 150mA make it ideal for extending battery life in wireless sensor nodes, where the regulator operates efficiently near the battery's end-of-life voltage.
Precision Analog Front-Ends
With 85dB PSRR at 100Hz, this LDO provides a clean, stable 2.8V rail for sensitive analog circuits like op-amps and ADCs, minimizing power supply noise that could corrupt measurements.
Portable Medical Devices
