The Texas Instruments LP3985ITLX-285/NOPB is a precision low-dropout linear regulator delivering a fixed 2.85V output at up to 150mA. Its ultra-low 150µA quiescent current and 0.1V dropout at full load make it exceptionally efficient for battery-powered applications. Housed in a compact 5-DSBGA package, it offers excellent PSRR of 50dB at 1kHz, ensuring clean, stable power for sensitive analog and RF circuits.
- Extended Battery Life: Ultra-low 150µA quiescent current minimizes standby power draw, ideal for portable devices.
- High Efficiency at Low Dropout: 0.1V dropout at 150mA allows operation with minimal input-to-output voltage headroom, reducing power dissipation.
- Clean Output for Sensitive Circuits: 50dB PSRR at 1kHz filters supply noise, protecting precision analog and RF loads.
- Space-Saving Footprint: 5-DSBGA (1.41x1.08mm) package fits high-density PCB designs without sacrificing performance.
Portable Battery-Powered Devices
The low 150µA quiescent current and 0.1V dropout at 150mA make it ideal for extending battery life in wearables, hearing aids, and remote sensors where every microamp matters.
Precision Analog Supplies
With PSRR of 50dB at 1kHz, this LDO provides clean, stable power to sensitive analog circuits like op-amps, ADCs, and reference voltage sources, minimizing noise-induced errors.
