Instructions for Using REF02HZ:

1. Power Supply:

   • Ensure the supply voltage (V_CC) is within the range of 2.7V to 5.5V.
   • Use a decoupling capacitor (typically 0.1μF) close to the V_CC pin to minimize noise and improve stability.

2. Output Voltage:

   • The REF02HZ provides a stable output voltage of 2.048V under no load conditions at 25°C.
   • For best accuracy, keep the load current within the specified range (0mA to 10mA).

3. Line Regulation:

   • The line regulation is very low (0.0001%/V), ensuring minimal changes in output voltage with variations in supply voltage.

4. Load Regulation:

   • The load regulation is also low (0.005%/mA), maintaining a stable output voltage even with varying load currents.

5. Temperature Coefficient:

   • The temperature coefficient is 10 ppm/°C, indicating that the output voltage will change by 10 parts per million for each degree Celsius change in temperature.

6. Dropout Voltage:

   • The dropout voltage is 0.3V at a load current of 10mA, meaning the input voltage must be at least 0.3V higher than the output voltage for proper operation.

7. Quiescent Current:

   • The quiescent current is 50 μA under no load conditions, which is relatively low and helps in power efficiency.

8. Output Noise Voltage:

   • The output noise voltage is 10 μV_RMS over the frequency range of 0.1Hz to 10Hz, making it suitable for precision applications.

9. Short-Circuit Protection:

   • The device has built-in short-circuit protection, limiting the short-circuit current to 10mA when V_CC is 5V.

10. Operating Temperature:

    • The operating temperature range is from -40°C to 125°C, making it suitable for a wide range of environmental conditions.

Additional Notes:

• Always refer to the datasheet for more detailed information and specific application notes.
• Proper PCB layout and grounding techniques are crucial for optimal performance, especially in high-precision applications.
