Instructions for Using REF5025AIDGKT

1. Supply Voltage:

   • Ensure the supply voltage is within the range of 2.7V to 5.5V. The reference voltage output is 2.5V.

2. Quiescent Current:

   • The quiescent current is typically 35 μA. This low current consumption makes it suitable for battery-powered applications.

3. Line Regulation:

   • The line regulation is 10 ppm/V, indicating that the output voltage changes by 10 ppm for every 1V change in supply voltage.

4. Load Regulation:

   • The load regulation is 10 ppm/mA, meaning the output voltage changes by 10 ppm for every 1mA change in load current.

5. Temperature Coefficient:

   • The temperature coefficient is 10 ppm/°C, indicating the output voltage changes by 10 ppm for every 1°C change in temperature.

6. PSRR (Power Supply Rejection Ratio):

   • At 120 Hz, the PSRR is 85 dB, which means the reference can effectively reject power supply noise.

7. Initial Accuracy:

   • The initial accuracy is ±0.1%, ensuring high precision in voltage reference applications.

8. Operating Temperature:

   • The device operates over a temperature range from -40°C to 125°C.

9. Storage Temperature:

   • Store the device in an environment with a temperature range from -65°C to 150°C.

10. Layout Considerations:

    • Use a good PCB layout with short traces and proper grounding to minimize noise and ensure stable performance.
    • Place bypass capacitors close to the supply pins to filter out high-frequency noise.

11. Stability:

    • The REF5025AIDGKT is stable with any capacitive load, but for optimal performance, use a 1 μF ceramic capacitor on the output.

12. Handling Precautions:

    • Handle the device with care to avoid damage from electrostatic discharge (ESD). Use ESD-safe tools and work surfaces.

By following these instructions, you can ensure reliable and accurate operation of the REF5025AIDGKT voltage reference.
