The MP20041DGT-SS-LF-Z is a dual 300mA low dropout linear regulator offering a fixed 3.3V output. Its low 0.22V dropout voltage and high PSRR (72dB at 10kHz) ensure clean, stable power for noise-sensitive applications. Housed in a compact 8-TQFN package, it is ideal for space-constrained designs requiring two independent regulated rails.
- Dual Independent Outputs: Two 300mA channels provide design flexibility for powering separate analog and digital domains.
- Excellent Noise Rejection: 72dB PSRR at 10kHz filters high-frequency interference, ensuring clean power for sensitive circuits.
- Low Dropout Voltage: 0.22V typical dropout at full load maximizes efficiency in battery-powered systems.
- Compact Footprint: 8-TQFN (2x2mm) package saves valuable board space in portable electronics.
Dual-Supply Microcontroller Systems
Power a 3.3V MCU core and I/O from a single 3.3V rail with two independent 300mA outputs, ensuring stable operation for mixed-signal designs.
Noise-Sensitive Analog Front Ends
With 72dB PSRR at 10kHz, this regulator effectively filters high-frequency switching noise, making it ideal for precision ADC and sensor interfaces.
Compact Portable Devices
The 2x2mm TQFN package minimizes PCB footprint, perfect for space-constrained wearables and IoT modules requiring dual low-noise rails.
Battery-Powered Equipment
Low 0.22V dropout at 300mA extends usable battery life by allowing operation close to the battery's end-of-discharge voltage.
Multi-Channel Sensor Arrays
Two regulated outputs can power separate analog and digital sections of a sensor hub, preventing digital noise from coupling into sensitive measurements.
FPGA Auxiliary Supplies
Provide clean 3.3V for FPGA auxiliary logic and transceiver termination, with sufficient margin for transient load steps.
