Instructions for REF02AU/2K5

1. Power Supply Connection:

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

2. Output Configuration:

   • The output voltage (Vout) is typically 2.5V and does not require external adjustment for standard applications.
   • For no-load conditions, allow a warm-up period before measuring Vout.

3. Stability and Performance:

   • The REF02AU/2K5 offers excellent line and load regulation, ensuring stable output over varying input voltages and load currents.
   • Keep temperature variations within -40°C to +85°C for optimal performance, as the temperature coefficient affects output stability.

4. Dropout Consideration:

   • Ensure that the difference between Vcc and Vout remains above the dropout voltage (typically 0.6V at 100mA load) to maintain regulation.

5. Power Consumption:

   • The quiescent current is approximately 60μA, which should be considered in low-power applications.

6. Handling and Installation:

   • Handle with care to avoid damage from electrostatic discharge (ESD).
   • Follow manufacturer guidelines for PCB layout to ensure optimal performance and thermal management.
