The Microchip MCP1825-3002E/ET is a fixed 3.0V, 500mA low dropout linear regulator in a DDPAK-5 package. It features a low dropout voltage of 0.35V at full load and a low 220µA quiescent current, making it ideal for battery-powered and energy-efficient designs. With 60dB PSRR at 100Hz, it provides clean, stable power for noise-sensitive analog and digital circuits. The robust thermal package supports demanding industrial and automotive applications.
- High Efficiency in Battery Systems: The 0.35V dropout at 500mA allows operation closer to the battery's discharge threshold, extending runtime in portable devices.
- Low Power Consumption: A 220µA quiescent current minimizes standby power draw, critical for always-on IoT and wearable applications.
- Excellent Noise Rejection: 60dB PSRR at 100Hz effectively suppresses power supply ripple, ensuring clean power for precision analog and RF circuits.
- Robust Thermal Performance: The DDPAK-5 package efficiently dissipates heat, enabling reliable operation at full 500mA load in high-temperature environments.
