Instructions for Use:

1. Input Connection:

   • Connect the input voltage (VIN) to the input pin. Ensure the input voltage is within the specified range (1.8V to 5.5V).

2. Output Connection:

   • Connect the output pin (VOUT) to the load. The TSR2402R provides a fixed output voltage of 2.4V.

3. Ground Connection:

   • Ensure a common ground connection between the input and output circuits.

4. Capacitors:

   • Place a 1 μF ceramic capacitor close to the input pin to stabilize the input voltage.
   • Place a 1 μF ceramic capacitor close to the output pin to stabilize the output voltage.

5. Thermal Considerations:

   • Ensure adequate heat dissipation if operating at high output currents or in high ambient temperatures.

6. Shutdown Mode:

   • To enter shutdown mode, pull the SHDN pin low. The quiescent current will drop to 0.1 μA in this mode.

7. PCB Layout:

   • Keep the PCB traces short and wide to minimize inductance and resistance.
   • Use a ground plane to improve thermal performance and reduce noise.

8. Storage and Handling:

   • Store the device in a dry, cool environment.
   • Handle with care to avoid static damage. Use proper ESD protection.

9. Testing:

   • Before final assembly, test the regulator with a known load to ensure it meets the required specifications.

10. Compliance:

    • Ensure that the design complies with relevant safety and regulatory standards for your application.
