The Monolithic Power Systems MPQ2019GN-5-Z is a 300mA low dropout linear regulator with a fixed 5V output. It features an ultra-low quiescent current of 16 μA, making it ideal for battery-powered and always-on applications. The dropout voltage is 0.64V at full load, and the 8-SOIC-EP package provides good thermal performance.
- Ultra-Low Quiescent Current: 16 μA dramatically extends battery life in standby and active modes.
- Wide PSRR Range: 57dB to 51dB (100Hz-100kHz) ensures stable output across frequencies.
- Low Dropout: 0.64V @ 300mA improves efficiency.
- Compact SOIC-EP: Exposed pad enhances thermal dissipation.
