Instructions for Using REF5040AID

1. Supply Voltage:

   • Ensure the supply voltage (V_CC) is within the range of 2.7V to 5.5V.
   • Connect the supply voltage to the V_CC pin and ground to the GND pin.

2. Output Configuration:

   • The REF5040AID provides a stable 2.5V output. Connect the output pin (V_OUT) to your circuit where a precision voltage reference is required.
   • For best performance, use a low-ESR capacitor (e.g., ceramic) of 10nF to 100nF in parallel with the output to filter out high-frequency noise.

3. Load Regulation:

   • The device can source up to 10mA of output current. Ensure that the load does not exceed this limit to maintain accuracy and stability.

4. Thermal Management:

   • The operating temperature range is from -40°C to 125°C. If operating in extreme temperatures, ensure adequate heat dissipation to prevent overheating.

5. Power Supply Rejection Ratio (PSRR):

   • The REF5040AID has a high PSRR, which helps in rejecting noise from the power supply. However, it is recommended to use a clean, well-regulated power supply to minimize any potential noise issues.

6. Initial Accuracy:

   • The initial accuracy of the REF5040AID is ±0.1%. This means the output voltage will be within 0.1% of 2.5V at room temperature (25°C).

7. Temperature Coefficient:

   • The temperature coefficient is 5ppm/°C, indicating that the output voltage will change by 5 parts per million for each degree Celsius change in temperature.

8. Quiescent Current:

   • The quiescent current is typically 120μA. This is the current drawn by the reference itself and should be considered in low-power applications.

9. Dropout Voltage:

   • The dropout voltage is 0.5V, meaning the input voltage must be at least 0.5V higher than the output voltage for the reference to function correctly.

10. Storage and Handling:

    • Store the device in a dry, cool place to avoid moisture damage.
    • Handle the device with care to avoid static discharge, which can damage sensitive components.

By following these guidelines, you can ensure optimal performance and reliability of the REF5040AID in your application.
