Supply Voltage Setup:
- Ensure the supply voltage (VDD) is within the operating range of 2.7 V to 5.5 V.
Output Voltage Stability:
- The device provides a stable output voltage of 4.096 V. Verify that this voltage meets your application requirements.
Line Regulation:
- For optimal performance, ensure the line regulation remains within 30 ppm/V when the load current changes from 1 mA to 150 mA.
Load Regulation:
- Maintain load regulation within 10 ppm/mA when the input voltage is VOUT + 1.2 V and the load current varies from 1 mA to 150 mA.
Dropout Voltage Consideration:
- Operate the device with an input voltage at least 1.2 V higher than the output voltage when the load current is 150 mA.
Quiescent Current Management:
- The quiescent current is typically 80 μA under no-load conditions. This should be considered in low-power applications.
Initial Accuracy Check:
- After a 1-minute warm-up period, verify that the initial accuracy of the output voltage is within ±0.2%.
Temperature Coefficient Monitoring:
- Monitor the temperature coefficient to ensure it stays within ±5 ppm/°C over the operational temperature range.

Ensure all connections are secure and double-check the power supply and load specifications before operation.
