The MPQ2019GN-33 from Monolithic Power Systems is a fixed 3.3V, 300mA LDO linear regulator in an 8-SOIC-EP package. It features a low dropout voltage of 0.6V at full load and a quiescent current of 95 μA. With good PSRR and thermal performance, this regulator is designed for automotive and industrial applications requiring higher output current.
- Higher Output Current: 300mA capability supports more demanding loads than typical 150mA LDOs.
- Low Dropout: 0.6V dropout at 300mA improves efficiency and allows operation with lower input voltages.
- Excellent Thermal Performance: The 8-SOIC-EP package with exposed pad dissipates heat effectively.
- Automotive Grade: Designed for automotive applications, ensuring reliability in harsh environments.
Automotive Infotainment Systems
Provides a stable 3.3V rail for infotainment processors and audio DSPs. The 300mA output can handle moderate loads, and the exposed pad package aids thermal dissipation.
Industrial Automation
Powers PLCs and industrial sensors that require a reliable 3.3V supply. The low dropout of 0.6V ensures operation even with input voltage variations.
Networking Equipment
Ideal for routers and switches, providing a clean 3.3V supply for PHY chips and switch controllers.
Medical Monitoring Devices
For patient monitors and diagnostic equipment, this LDO offers stable power with good PSRR (45dB at 1kHz) to reject noise.
FPGA and CPLD Power
Can power the auxiliary logic of FPGAs and CPLDs that require 3.3V, ensuring reliable operation in prototyping and production.
Battery-Powered Equipment
With 95 μA quiescent current, it is suitable for battery-powered devices that need higher output current than the MP2013A series.
