Instructions for XR76112EL-F

1. Power Supply Connection:

   • Connect the supply voltage (VDD) between 2.7V and 5.5V to the input pin.
   • Ensure proper decoupling capacitors are placed close to the input and output pins to maintain stability.

2. Output Configuration:

   • The device provides a fixed output voltage of 3.3V under no-load conditions.
   • For optimal performance, use an output capacitor of at least 1μF.

3. Thermal Considerations:

   • The device includes thermal shutdown protection that activates at approximately 160°C.
   • Ensure adequate heat dissipation if operating at higher current levels or in high ambient temperatures.

4. Load Regulation:

   • The load regulation is specified as 0.5% from 0 to 100mA, ensuring stable output voltage over a range of load currents.

5. Line Regulation:

   • Line regulation is 0.2% across the input voltage range of 2.7V to 5.5V, providing consistent output voltage despite input voltage variations.

6. Short Circuit Protection:

   • The device limits the short circuit current to approximately 280mA to protect against damage during fault conditions.

7. Dropout Voltage:

   • Operates efficiently with a low dropout voltage of 1.2V at an output current of 100mA, allowing for operation closer to the input supply voltage.

8. Quiescent Current:

   • Maintains a low quiescent current of 10μA at 5V supply, making it suitable for battery-operated applications.
