The Monolithic Power Systems MPQ2019GN-P is a high-voltage LDO regulator delivering a fixed 15V output with up to 300mA current. Its ultra-low 15 μA quiescent current and 0.55V dropout at full load make it exceptionally efficient. With PSRR of 45dB at 1kHz and 57-51dB from 100Hz to 100kHz, it provides clean power for noise-sensitive applications. The 8-SOIC-EP package ensures excellent thermal dissipation.
- High Efficiency: 15 μA quiescent current and 0.55V dropout reduce power loss.
- Wide Bandwidth Noise Rejection: 57-51dB PSRR from 100Hz to 100kHz.
- High Voltage Operation: Supports input voltages well above 15V.
- Thermal Performance: Exposed pad package enhances heat dissipation.
