Instructions for REF5025IDGKR

1. Power Supply Requirements:

   • Ensure the input voltage (VIN) is within the range of 2.7V to 5.5V.

2. Output Voltage Stability:

   • The output voltage (VOUT) is fixed at 2.5V. For optimal performance, maintain a stable input voltage and load conditions.

3. Load Regulation:

   • To ensure minimal deviation in output voltage, keep the load current (ILOAD) between 1mA and 100mA.

4. Temperature Considerations:

   • Operate the device within the temperature range of -40°C to +85°C to maintain specified accuracy and stability.

5. Power Supply Rejection Ratio (PSRR):

   • For effective noise rejection, especially at frequencies around 1kHz, verify that the PSRR is maintained at or above 65dB.

6. Supply Current:

   • Monitor the operating supply current (ISUPPLY) to ensure it does not exceed 120μA under typical operating conditions.

7. Mounting and Handling:

   • Handle with care to avoid damage to the pins and ensure proper mounting on the PCB to prevent thermal issues and electrical shorts.

8. Initial Setup:

   • Before deployment, calibrate the reference voltage if necessary to meet the initial accuracy requirements of ±0.1%.

9. Storage and Packaging:

   • Store in a dry environment and follow anti-static precautions to protect against ESD damage.
