Instructions:

1. Power Supply Connection:

   • Connect the input voltage within the specified range (3.5V to 16V) to the V_IN pin.
   • Ensure proper decoupling capacitors are placed close to the input and output pins to stabilize the voltage.

2. Output Configuration:

   • The TEA1753LT/N1 provides a fixed 3.3V output. No external components are required for setting the output voltage.

3. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at high temperatures or under heavy loads.
   • Keep the device within the operating temperature range (-40°C to +85°C).

4. Shutdown Mode:

   • To enter shutdown mode, pull the SHDN pin low. This reduces the quiescent current to approximately 10μA.

5. Capacitor Selection:

   • Use ceramic capacitors with X7R dielectric for both input and output filtering. Typical values are 1μF for input and 10μF for output.

6. PCB Layout:

   • Place the device and its associated components as close together as possible to minimize noise and improve performance.
   • Keep traces short and wide to reduce resistance and inductance.

7. Handling Precautions:

   • Handle the device with care to avoid damage from electrostatic discharge (ESD).
   • Follow standard precautions for surface-mount technology (SMT) devices during assembly.

8. Storage:

   • Store the device in a dry environment within the storage temperature range (-65°C to +150°C).
