The MP20051DN-LF-Z from Monolithic Power Systems is a 5V fixed-output LDO linear regulator capable of delivering 1A of current. It features a low dropout voltage of 0.28V at full load, enabling efficient regulation from input voltages as low as 0.8V. With a quiescent current of 600µA and excellent PSRR across a wide frequency range, it is designed for noise-sensitive applications. The 8-SOICE package is compact and suitable for space-constrained PCB layouts.
- High Efficiency at Low Dropout: The 0.28V dropout at 1A minimizes power dissipation, improving system efficiency and reducing heat generation.
- Excellent Noise Rejection: With PSRR of 65dB at 100Hz and 33dB at 1MHz, it effectively filters high-frequency noise, ideal for RF and precision analog circuits.
- Wide Input Voltage Range: Operates from 0.8V up to 5.5V, providing flexibility in multi-rail systems and supporting low-voltage core supplies.
- Robust Thermal Performance: The 8-SOICE package offers good thermal conductivity, ensuring reliable operation at 1A load currents.
FPGA and DSP Core Power
The 5V fixed output and 1A current capability make it ideal for powering FPGA and DSP core rails that require a stable, low-noise supply.
Post-Regulation for Switching Converters
With a low 0.28V dropout at 1A, it can efficiently clean up the output of a buck converter, reducing ripple and providing a clean 5V rail.
Industrial Sensor Interfaces
Its wide input range from 0.8V allows it to operate from various intermediate buses, providing a regulated 5V supply for industrial sensors and transceivers.
Automotive Infotainment Systems
The high PSRR of 65dB to 33dB (100Hz to 1MHz) helps reject noise from automotive power lines, ensuring clean power for infotainment processors.
