The STMicroelectronics LDK220PU50R is a low-dropout linear regulator delivering a fixed 5.0V output with up to 200mA of current. It features a quiescent current of 90 µA and a dropout voltage of just 0.35V at full load. With PSRR of 55dB at 120Hz, it effectively filters low-frequency noise. The ultra-compact 6-DFN package is perfect for space-constrained industrial and automotive applications.
- Low Dropout Voltage: 0.35V at 200mA maximizes efficiency and allows operation from lower input voltages.
- Compact DFN Package: The 1.2x1.3mm footprint saves significant PCB space compared to traditional SOT-23 packages.
- Good Low-Frequency Noise Rejection: 55dB PSRR at 120Hz effectively filters mains-related ripple.
- Balanced Power Consumption: 90 µA quiescent current offers a good trade-off between performance and battery life.
