Instructions for Use:

1. Supply Voltage (V_IN):

   • Ensure the supply voltage is within the range of 2.7V to 5.5V.
   • Avoid exceeding the maximum supply voltage to prevent damage.

2. Output Voltage (V_OUT):

   • The output voltage is fixed at 3.3V under no load conditions.
   • Use appropriate decoupling capacitors to stabilize the output.

3. Quiescent Current (I_Q):

   • The quiescent current is typically 100μA when the input voltage is 3.3V.
   • This value helps in power budgeting for low-power applications.

4. Dropout Voltage (V_DROP):

   • The dropout voltage is typically 150mV at an output current of 10mA.
   • Ensure that the input voltage is at least 150mV higher than the output voltage to maintain regulation.

5. Initial Accuracy (ΔV_OUT):

   • The initial accuracy is ±0.02% at 25°C.
   • This parameter is crucial for precision applications.

6. Temperature Coefficient (T_C):

   • The temperature coefficient is 5ppm/°C over the operating temperature range.
   • This indicates how the output voltage changes with temperature.

7. Load Regulation (ΔV_OUT/ΔI_OUT):

   • The load regulation is 5ppm/mA from 100μA to 10mA.
   • This parameter ensures that the output voltage remains stable under varying load conditions.

8. Line Regulation (ΔV_OUT/ΔV_IN):

   • The line regulation is 5ppm/V from 2.7V to 5.5V.
   • This ensures that the output voltage remains stable despite changes in the input voltage.

9. Output Noise Voltage (V_N):

   • The output noise voltage is 6μV_RMS over the frequency range of 0.1Hz to 10Hz.
   • Use bypass capacitors to further reduce noise if necessary.

10. Short-Circuit Current (I_SC):

    • The short-circuit current is limited to 30mA when the input voltage is 3.3V.
    • Ensure that the output is not short-circuited for extended periods to avoid damage.

11. Operating Temperature Range (T_A):

    • The device operates reliably from -40°C to 125°C.
    • Avoid operating the device outside this range to prevent performance degradation or failure.

12. Storage Temperature Range (T_STG):

    • The device can be stored from -65°C to 150°C.
    • Ensure proper storage conditions to maintain device integrity.
