The MPQ2019GN-5-P from Monolithic Power Systems is a low-dropout linear regulator delivering a fixed 5V output with up to 300mA current. Its 15 μA quiescent current and 0.64V dropout at full load make it ideal for battery-operated and always-on systems. The 8-SOIC-EP package provides excellent thermal performance, while PSRR of 45dB at 1kHz ensures clean power for sensitive analog loads.
- Extended Battery Life: 15 μA quiescent current minimizes standby drain, ideal for portable and IoT devices.
- High Efficiency at Low Dropout: 0.64V dropout at 300mA allows operation close to the output voltage, reducing power loss.
- Clean Output for Analog Circuits: 45dB PSRR at 1kHz filters switching noise, ensuring stable rails for precision sensors.
- Thermally Efficient Package: 8-SOIC-EP with exposed pad improves heat dissipation, enabling reliable operation at full load.
Battery-Powered IoT Sensors
The ultra-low 15 μA quiescent current extends battery life in always-on IoT sensor nodes, where standby power dominates. The 300mA output supports periodic high-current radio bursts.
Automotive ECU Power Rails
With a 5V fixed output and 300mA capability, it can power microcontroller I/O and sensor interfaces in automotive ECUs. The exposed pad package aids thermal dissipation in under-hood environments.
Portable Medical Devices
Low dropout of 0.64V at full load allows operation from a single Li-ion cell (3.7V nominal) down to 5.64V input, maximizing usable battery capacity in glucose monitors and wearable patches.
Industrial Control Modules
The 45dB PSRR at 1kHz filters switching noise from upstream DC-DC converters, providing clean 5V rails for analog sensor conditioning circuits in PLCs and motor drives.
Smart Home Hubs
Stable 5V output with 300mA capacity powers Wi-Fi modules and LED indicators simultaneously. The 8-SOIC-EP package fits compact hub PCBs with minimal footprint.
Telecom Line Cards
Wide PSRR (57dB at 100Hz to 51dB at 100kHz) suppresses 50/60Hz hum and high-frequency ripple from telecom power buses, ensuring clean supply for line driver ICs.
