Instructions for Using REF5025AIDR REF5025:
Power Supply:
- Ensure the input voltage (VIN) is within the specified range of 4.5V to 18V.
- The device can handle a maximum output current of 20mA continuously.
Output Voltage:
- The output voltage (VOUT) is fixed at 2.5V under no load conditions.
- For accurate operation, ensure the load regulation and line regulation are within the specified limits.
Temperature Considerations:
- The temperature coefficient is 5 ppm/°C, which means the output voltage will vary slightly with temperature changes.
- The initial accuracy at room temperature (25°C) is ±0.1%.
Quiescent Current:
- The quiescent current (IQ) is typically 60 μA at 5V input and no load.
Dropout Voltage:
- The dropout voltage (VDROP) is 1.3V at an output current of 10mA. This means the input voltage should be at least 1.3V higher than the output voltage to maintain regulation.
Power Dissipation:
- The maximum power dissipation is 180 mW. Ensure adequate heat sinking or cooling if operating near this limit.
Stability and Layout:
- Use a 1 μF ceramic capacitor on the output to ensure stability.
- Place the capacitor as close as possible to the output pin to minimize parasitic inductance.
Handling and Storage:
- Handle the device with care to avoid static damage.
- Store in a dry environment to prevent moisture-related issues.
Application Notes:
- Refer to the datasheet for detailed application notes and circuit diagrams.
- For precision applications, consider using a low-noise power supply and shielding to minimize interference.
By following these guidelines, you can ensure optimal performance and reliability of the REF5025AIDR REF5025 voltage reference.
