Instructions for Use:

1. Input Voltage (VIN):

   • Ensure the input voltage is within the specified range of 4.5V to 28V.
   • Avoid exceeding the maximum input voltage to prevent damage to the device.

2. Output Voltage (VOUT):

   • The output voltage can be adjusted between 0.8V and 20V. Use the external resistor network to set the desired output voltage.
   • Refer to the datasheet for the specific resistor values required for different output voltages.

3. Output Current (IOUT):

   • The device can provide a continuous output current up to 3A. For optimal performance, keep the load current within the typical range of 1.5A.
   • Ensure adequate heat dissipation if operating at higher currents.

4. Quiescent Current (IQ):

   • The quiescent current is typically 70μA at 12V input. This value helps in determining the efficiency of the regulator in low-load conditions.

5. Dropout Voltage (VDROPOUT):

   • The dropout voltage is the minimum difference between the input and output voltages required to maintain regulation. It is typically 0.5V at 3A output current and 5V input.

6. Regulation:

   • Load regulation and line regulation are both specified as 0.1% to 0.5%. These parameters indicate the stability of the output voltage under varying load and input conditions.

7. Ripple Rejection:

   • The device provides ripple rejection of 60dB to 80dB at 120Hz, which helps in filtering out noise from the input supply.

8. Temperature Considerations:

   • The operating temperature range is -40°C to 125°C. Ensure the device is used within this range to avoid thermal stress.
   • The storage temperature range is -65°C to 150°C, which is useful for handling and storage before installation.

9. PCB Layout:

   • Place the input and output capacitors close to the device to minimize parasitic inductance and improve transient response.
   • Use a ground plane to help with heat dissipation and reduce electromagnetic interference (EMI).

10. Safety:

    • Always follow proper handling and safety guidelines when working with electronic components.
    • Ensure that the input power supply is properly rated and protected with appropriate fuses or circuit breakers.
