Instructions for TPS82140SILR

1. Power Connections:

   • Connect the input voltage (VIN) to the positive terminal of the power supply.
   • Ensure the ground (GND) is properly connected to the common ground of the system.

2. Output Configuration:

   • The device has a fixed output voltage of 1.8V, which does not require external resistors for setting the output voltage.

3. Capacitor Selection:

   • Use a ceramic capacitor with low ESR for the input and output capacitors to ensure stability.
   • Recommended values are typically 1渭F for both input and output.

4. Thermal Considerations:

   • Place the device in an area with adequate airflow or consider adding a heat sink if operating at high temperatures or currents.

5. Shutdown Functionality:

   • The shutdown pin can be used to turn off the device by pulling it low. It requires less than 0.1渭A in shutdown mode.

6. PCB Layout:

   • Keep the traces short and wide between the input capacitor, inductor, and the IC to minimize parasitic inductance and resistance.
   • Ensure proper grounding and shielding to avoid noise interference.

7. Handling Precautions:

   • Handle the device with care as it is sensitive to electrostatic discharge (ESD).
   • Follow standard ESD handling procedures during installation and testing.
