Instructions for Use:

1. Input Connection:

   • Connect the input voltage (V_IN) to the VIN pin.
   • Ensure the input voltage is within the specified range (4.5V to 16V).

2. Output Configuration:

   • Set the output voltage (V_OUT) using the external resistor divider network connected to the FB (feedback) pin.
   • Refer to the datasheet for specific resistor values based on desired output voltage.

3. Output Load:

   • The PM50CLA120 can provide up to 1.2A continuous output current.
   • Ensure the load does not exceed this limit to avoid overheating or damage.

4. Thermal Management:

   • The device is designed to operate within a temperature range of -40°C to 85°C.
   • For extended operation at high temperatures, consider adding a heatsink or ensuring adequate airflow.

5. Efficiency:

   • The typical efficiency is 90% under nominal conditions.
   • Optimize the design for maximum efficiency by minimizing trace lengths and using low ESR capacitors.

6. Quiescent Current:

   • In shutdown mode, the quiescent current is approximately 20μA.
   • Use the EN (enable) pin to control the power state of the device.

7. Storage:

   • Store the device in a dry environment with temperatures between -65°C and 150°C to ensure long-term reliability.

8. Package:

   • The PM50CLA120 comes in a SOT-23-5 package.
   • Follow standard PCB layout guidelines for surface mount components to ensure proper soldering and mechanical stability.
