Instructions for Use:

1. Input Connection:

   • Connect the input voltage to the VIN pin. Ensure the input voltage is within the specified range (4.5V to 40V).

2. Output Configuration:

   • For fixed output voltage (5V), connect the output directly from the VOUT pin.
   • For adjustable output voltage, use an external resistor divider connected to the ADJ pin. The formula for calculating the output voltage is: [ V_ = 1.23 left(1 + fracright) ] where ( R_1 ) is the resistor connected between VOUT and ADJ, and ( R_2 ) is the resistor connected between ADJ and GND.

3. Ground Connection:

   • Connect the ground (GND) pin to the common ground of the system.

4. Capacitors:

   • Place a 1μF ceramic capacitor close to the VIN pin to filter input noise.
   • Place a 1μF ceramic capacitor close to the VOUT pin to stabilize the output.

5. Thermal Management:

   • Ensure adequate heat dissipation if operating at high power levels or in high ambient temperatures. The thermal shutdown temperature is 160°C.

6. Short-Circuit Protection:

   • The device has built-in short-circuit protection, limiting the output current to approximately 1.5A.

7. Operating Temperature:

   • Operate the device within the specified temperature range (-40°C to 125°C) to ensure reliable performance.

8. Storage Temperature:

   • Store the device in a temperature range of -65°C to 150°C to prevent damage.

9. Handling Precautions:

   • Handle the device with care to avoid static discharge, which can damage sensitive components. Use proper ESD protection practices.
