The Texas Instruments LP5900SDX-1.8/NOPB is a fixed-output LDO regulator providing 150mA at 1.8V. With a low dropout of 0.15V at full load and excellent PSRR (85dB at 100Hz), it delivers clean, stable power for noise-sensitive applications. The 6-WSON package offers a compact solution for portable electronics.
- Excellent Low-Frequency PSRR: 85dB at 100Hz effectively filters mains hum and low-frequency ripple.
- Low Dropout: 0.15V at 150mA maximizes efficiency in low-headroom designs.
- Low Noise: High PSRR across frequency range ensures clean output for analog and RF circuits.
- Compact WSON Package: 2.2x2.5mm footprint ideal for space-constrained PCBs.
