Instructions for Use:

1. Input Voltage (Vin):

   • The input voltage should be within the range of 4.75V to 18V.
   • Ensure the input voltage is stable and does not exceed the maximum rating to avoid damage.

2. Output Voltage (Vout):

   • The output voltage is regulated to 5.0V under no load conditions.
   • Use appropriate capacitors on the input and output to stabilize the voltage and reduce ripple.

3. Load Regulation:

   • The load regulation is typically 1.0% over the load range from 0mA to 1000mA.
   • Ensure the load does not exceed 1000mA to maintain regulation.

4. Dropout Voltage:

   • The dropout voltage is typically 2.0V at a load current of 1000mA.
   • Keep the input voltage at least 2.0V higher than the output voltage to ensure proper operation.

5. Quiescent Current:

   • The quiescent current is typically 5.0mA when no load is present.
   • This current is drawn by the regulator itself and should be considered in power budgeting.

6. Shutdown Current:

   • The shutdown current is typically 0.5μA when the device is in shutdown mode.
   • Use the shutdown pin to turn off the regulator when not in use to save power.

7. Output Ripple Rejection:

   • The output ripple rejection is typically 70dB over the frequency range from 10Hz to 100kHz.
   • Use bypass capacitors to further reduce ripple if necessary.

8. Thermal Shutdown:

   • The device will shut down if the junction temperature exceeds 160°C to prevent damage.
   • Ensure adequate heat sinking or cooling to keep the device within the operating temperature range.

9. Operating Temperature:

   • The operating junction temperature range is from -40°C to 125°C.
   • Ensure the device is used within this range to avoid thermal issues.

10. Capacitor Selection:

    • Use ceramic capacitors with low ESR for input and output filtering.
    • Typical values are 10μF for input and 10μF for output, but these can be adjusted based on specific application requirements.
