Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the specified range of 2.9V to 5.5V.
   • Avoid applying voltages outside this range to prevent damage to the device.

2. Output Voltage (VOUT):

   • The output voltage is fixed at 3.3V. No external components are required for voltage regulation.

3. Output Current (IOUT):

   • The device can provide up to 1.0A of continuous output current.
   • For higher currents, consider using a heat sink or ensuring adequate cooling.

4. Quiescent Current (IQ):

   • The quiescent current is typically 40 μA when no load is connected.
   • This low quiescent current makes the device suitable for battery-powered applications.

5. Efficiency (η):

   • The typical efficiency is 85% at full load.
   • Efficiency can be improved by minimizing the difference between VIN and VOUT.

6. Dropout Voltage (VDROPOUT):

   • The dropout voltage is typically 180 mV at 1.0 A.
   • Ensure that the input voltage is at least 180 mV above the desired output voltage to maintain regulation.

7. Load and Line Regulation:

   • The load regulation is 1.0%, meaning the output voltage will vary by 1.0% over the entire load range.
   • The line regulation is 0.2% per volt, indicating how much the output voltage changes with variations in input voltage.

8. Ripple Rejection:

   • The device provides 60 dB ripple rejection at 100 Hz, effectively reducing input ripple on the output.

9. Thermal Shutdown (TSD):

   • The device will shut down if the temperature exceeds 160°C.
   • It will automatically recover when the temperature drops below 130°C.

10. Storage Temperature (TSTG):

    • Store the device in an environment where the temperature ranges from -40°C to 125°C.

11. Package Type:

    • The FSL137MRIN is available in a standard SO-8 surface mount package.
    • Follow standard surface mount soldering guidelines for installation.

By adhering to these parameters and instructions, you can ensure reliable operation of the FSL137MRIN in your application.
