Instructions for Using NCP81061

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.7V to 5.5V.
   • Use appropriate input capacitors (e.g., 1渭F ceramic) to stabilize the input voltage.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted using external resistors R1 and R2.
   • The formula to calculate the output voltage is: ( V_ = 1.2V left(1 + fracright) ).

3. Output Current (IOUT):

   • The device can provide up to 1000mA of continuous output current.
   • Ensure the load does not exceed this limit to avoid overheating or damage.

4. Quiescent Current (IQ):

   • The quiescent current is typically 30渭A and should be considered when designing low-power applications.

5. Dropout Voltage (VDROPOUT):

   • The dropout voltage is the minimum difference between the input and output voltages required for the regulator to maintain regulation.
   • At maximum load, the dropout voltage is typically 150mV to 300mV.

6. Load Regulation:

   • The change in output voltage due to changes in load is typically 0.5% to 1.0%.

7. Line Regulation:

   • The change in output voltage due to changes in input voltage is typically 0.1% to 0.2% per volt.

8. Thermal Shutdown (TSD):

   • The device will shut down if the junction temperature exceeds 160掳C to prevent damage.
   • Allow the device to cool down before it automatically restarts.

9. Short-Circuit Protection (SCP):

   • The device has built-in short-circuit protection that will automatically recover once the fault is removed.

10. Operating Temperature (TOPR):

    • The operating temperature range is from -40掳C to 125掳C.
    • Ensure the ambient temperature and heat dissipation are managed to keep the device within this range.

11. Storage Temperature (TSTG):

    • The storage temperature range is from -65掳C to 150掳C.
    • Store the device in a dry, cool place to ensure long-term reliability.

By following these parameters and instructions, you can effectively use the NCP81061 in your application.
