The Monolithic Power Systems MPQ2019GN-33-AEC1-P is an automotive-grade LDO regulator providing 300mA at fixed 3.3V. Featuring 16 μA quiescent current and 0.64V dropout at full load, it balances efficiency with performance. The 8-SOIC-EP package enhances thermal management, while PSRR of 45dB at 1kHz ensures stable operation in noisy environments.
- AEC-Q1 Qualified: Designed for demanding automotive applications.
- Low Power: 16 μA quiescent current reduces standby consumption.
- Thermal Efficiency: Exposed pad package improves heat dissipation.
- Broad PSRR: 57dB~51dB from 100Hz to 100kHz filters wideband noise.
