The MPQ2019GN-33 is a fixed 3.3V low-dropout linear regulator from Monolithic Power Systems. It delivers up to 300mA with an ultra-low dropout of just 0.6V. The 8-SOIC-EP package with exposed pad ensures excellent thermal performance. With 95 μA quiescent current and 45dB PSRR at 1kHz, it balances efficiency and noise performance for a wide range of applications.
- Higher Current Capacity: 300mA output supports more demanding loads than typical 150mA LDOs.
- Ultra-Low Dropout: 0.6V at 300mA maximizes efficiency and usable input range.
- Excellent Thermal Management: Exposed pad in 8-SOIC-EP package dissipates heat effectively.
- Good Ripple Rejection: 45dB PSRR at 1kHz ensures clean power for digital and analog circuits.
Higher-Current Portable Devices
With 300mA output and 0.6V dropout, it efficiently powers FPGAs, DSPs, and other higher-current loads.
Industrial Sensor Modules
The 8-SOIC-EP package with exposed pad aids heat dissipation in industrial temperature environments.
Networking Equipment
Provides a stable 3.3V rail for Ethernet PHYs and switches, with 45dB PSRR at 1kHz to reduce noise.
