The MP2019GN-33-P from Monolithic Power Systems is a fixed 3.3V low-dropout linear regulator designed for power-sensitive applications. It delivers up to 300mA with a dropout voltage of just 0.64V at full load. Its 16 μA quiescent current minimizes standby power, while the 8-SOIC-EP package provides excellent thermal performance. Ideal for battery-powered and industrial systems requiring a clean, stable voltage rail.
- Extended Battery Life: Ultra-low 16 μA quiescent current reduces standby drain in portable devices.
- High Efficiency at Low Dropout: 0.64V dropout at 300mA allows operation from nearly depleted batteries.
- Clean Output: PSRR of 45dB at 1kHz filters supply noise for sensitive analog circuits.
- Thermal Management: Exposed pad in 8-SOIC-EP package improves heat dissipation for reliable high-current operation.
Battery-Powered IoT Sensors
The ultra-low 16 μA quiescent current extends battery life in always-on IoT sensor nodes, where standby power dominates.
Portable Medical Devices
With a stable 3.3V rail and 300mA capability, it powers microcontrollers and analog front-ends in glucose monitors and pulse oximeters.
Industrial Control Modules
The 8-SOIC-EP package with exposed pad aids thermal dissipation, supporting reliable operation in 24V industrial bus-powered sensors.
Automotive Infotainment
Provides clean 3.3V for CAN transceivers and audio codecs, with PSRR of 45dB at 1kHz to reject alternator noise.
