Instructions for Use:

1. Input Voltage (Vin):

   • Ensure the input voltage is within the specified range of 6.5V to 35V.
   • Avoid applying voltages outside this range to prevent damage to the device.

2. Output Voltage (Vout):

   • The output voltage is regulated to 5V 卤 0.25V.
   • The device can supply up to 1.5A of current continuously.

3. Quiescent Current (IQ):

   • The quiescent current is typically 5mA and should not exceed 10mA when no load is applied.

4. Dropout Voltage (VD):

   • The dropout voltage is typically 1.7V at full load (1.5A). Ensure the input voltage is at least 1.7V higher than the output voltage to maintain regulation.

5. Thermal Shutdown (TSD):

   • The device will automatically shut down if the temperature exceeds 160掳C to protect against overheating.

6. Operating and Storage Temperature:

   • The device can operate in temperatures ranging from -40掳C to 125掳C.
   • Store the device in temperatures between -65掳C and 150掳C.

7. Mounting and Layout:

   • Use appropriate heat sinking if operating at high currents or in high ambient temperatures.
   • Ensure proper PCB layout to minimize inductance and improve thermal performance.

8. Capacitors:

   • Place a 0.33渭F ceramic capacitor close to the input pin and a 0.1渭F ceramic capacitor close to the output pin to ensure stability and reduce noise.

9. Polarity:

   • Ensure correct polarity when connecting the input and output. Reversing the polarity can damage the device.

10. Testing:

    • Before finalizing the design, test the circuit under various conditions to ensure it meets the required specifications.
