Instructions for REF43-043S:

1. Power Supply Connection:

   • Connect the input voltage (VIN) between the V+ and GND pins. Ensure the input voltage is within the specified range of 2.7V to 5.5V.

2. Output Configuration:

   • The output voltage (VOUT) can be set using external resistors or by selecting a fixed output version. Verify the desired output voltage is within the range of 1.232V to 4.096V.

3. Load Regulation:

   • For optimal performance, ensure the load current (ILOAD) does not exceed 10mA. This minimizes the impact on load regulation.

4. Thermal Management:

   • Operate the device within the temperature range of -40°C to +85°C to maintain the specified temperature coefficient and ensure stable operation.

5. Bypass Capacitors:

   • Place a bypass capacitor close to the V+ pin to minimize noise and transient effects. A typical value is 0.1μF.

6. PCB Layout Considerations:

   • Maintain short and wide traces for power connections to reduce parasitic inductance and resistance.
   • Keep sensitive analog signals away from noisy digital lines to avoid interference.

7. Storage and Handling:

   • Store the device in a dry environment to prevent moisture damage.
   • Handle with care to avoid static discharge which can damage the internal components.
