The MP20046DN-S-LF from Monolithic Power Systems is a fixed 3.3V linear regulator capable of delivering up to 2A of output current. With a low dropout voltage of 0.4V at full load and a quiescent current of just 300 μA, it balances efficiency with performance. Its high PSRR of 70dB at 100Hz makes it suitable for noise-sensitive applications. Housed in an 8-SOICE package, this LDO is designed for space-constrained industrial and consumer electronics.
- High Output Current: Delivers up to 2A, supporting power-hungry digital loads without needing multiple regulators.
- Excellent Ripple Rejection: 70dB PSRR at 100Hz ensures clean power for sensitive analog and RF circuits.
- Low Dropout Voltage: 0.4V dropout at 2A maximizes efficiency and allows operation with minimal headroom.
- Low Quiescent Current: 300 μA quiescent current reduces power consumption in battery-operated devices.
High-Current Digital Loads
Power FPGAs, DSPs, or ASIC cores requiring up to 2A with a stable 3.3V rail. The low 0.4V dropout at full load ensures efficient operation even when the input supply is close to 3.7V.
Noise-Sensitive Analog Circuits
With 70dB PSRR at 100Hz, this LDO effectively filters low-frequency ripple from switching pre-regulators, making it ideal for precision analog front-ends, audio codecs, and sensor signal conditioning.
Industrial Control Systems
Provide a clean, regulated 3.3V supply for microcontrollers, I/O interfaces, and communication modules in industrial environments where input voltage fluctuations are common.
Networking and Telecom Equipment
Power high-speed transceivers and PHY chips that demand low noise and tight voltage regulation. The 2A capability supports multiple loads from a single regulator.
Battery-Powered Devices
The 300 μA quiescent current helps extend battery life in portable instruments and wireless devices while maintaining a stable output as the battery voltage declines.
Post-Regulation for DC-DC Converters
Use after a buck converter to eliminate switching noise and provide a clean, low-ripple 3.3V rail for mixed-signal systems, improving overall system performance.
