The MPQ2019GN is an adjustable LDO from Monolithic Power Systems, delivering up to 300mA at a typical 15V output. Its 95 µA quiescent current makes it suitable for battery-powered and automotive applications. The 8-SOIC-EP package provides a compact footprint with exposed pad for heat dissipation. Dropout is typically 0.55V at full load.
- Ultra-Low Quiescent Current: 95 µA extends battery life in standby modes.
- High Output Voltage: Supports 15V rails for industrial and automotive loads.
- Low Dropout: 0.55V at 300mA maximizes efficiency in tight margin designs.
- Automotive Grade Option: AEC-Q100 qualified variants available (MPQ2019GN-AEC1).
Automotive Always-On Modules
The 95 µA quiescent current is critical for battery-connected ECUs that must remain in standby without draining the vehicle battery.
High-Voltage Sensor Interfaces
With a 15V output, it can power industrial sensors requiring higher compliance voltages, such as 4-20mA loops.
Telecom Line Cards
The low dropout of 0.55V at 300mA allows operation from a 15.5V rail with minimal headroom, reducing power dissipation.
Portable Test Equipment
Its adjustable output lets designers set precise voltages for calibration circuits, while the SOIC-EP package aids thermal management.
Battery Management Systems
Regulates 15V for cell-balancing ICs, with the low quiescent current preserving pack charge during storage.
Industrial PLC Analog Outputs
Provides a stable 15V reference for DACs and op-amps, with 45dB PSRR at 1kHz reducing switching noise.
