Instructions for UPA1730G

1. Power Supply Connection:

   • Connect the input voltage (V_IN) within the specified range of 2.7V to 5.5V.
   • Ensure the output capacitor is connected close to the output pin for stability.

2. Output Configuration:

   • The UPA1730G provides a fixed output voltage of 3.3V. No external resistors are required for setting the output voltage.

3. Load Handling:

   • The device can supply up to 300mA of load current continuously. Ensure the load does not exceed this limit to avoid overheating or damage.

4. Thermal Management:

   • The maximum power dissipation is 680mW at an ambient temperature of 25°C. Proper heat sinking may be necessary for applications approaching this limit.

5. Shutdown Operation:

   • To place the regulator in shutdown mode, pull the SHDN pin low. This reduces the supply current to approximately 0.1μA.

6. Capacitor Selection:

   • Use capacitors with adequate ripple current ratings and ensure they have low ESR (Equivalent Series Resistance) for optimal performance and stability.

7. Operating and Storage Temperatures:

   • Operate the device within the temperature range of -40°C to +85°C. Store the device between -65°C and +150°C.

8. Handling Precautions:

   • Handle with care to prevent electrostatic discharge (ESD). Use appropriate ESD protection measures during installation and handling.
