The LP3985ITLX-3.3/NOPB is a precision low dropout linear regulator delivering a fixed 3.3V output with up to 150mA current capability. Its ultra-low 0.1V dropout voltage at full load ensures efficient operation even with tight input-output margins. Housed in a miniature 5-DSBGA package, this regulator features a low 150µA quiescent current and excellent PSRR performance, making it an ideal choice for battery-powered and noise-sensitive portable applications.
- Extended Battery Life: Ultra-low 150µA quiescent current minimizes standby power consumption in portable devices.
- High Efficiency at Low Dropout: 0.1V dropout at 150mA allows operation with minimal input-output voltage difference, reducing power dissipation.
- Clean Power Delivery: PSRR of 50dB at 1kHz and 40dB at 10kHz effectively filters supply noise for sensitive analog and RF circuits.
- Compact Footprint: 5-DSBGA (1.5x1.2) package saves critical board space in space-constrained designs.
