Instructions for Using U1660G

1. Supply Voltage (Vcc):

   • Ensure the supply voltage is within the range of 2.7V to 5.5V. Operating outside this range can damage the device.

2. Operating Temperature (Toper):

   • The device is designed to operate within a temperature range of -40°C to 85°C. Avoid exceeding these limits to prevent performance degradation or failure.

3. Storage Temperature (Tstg):

   • Store the device in an environment where temperatures range from -65°C to 150°C to ensure long-term reliability.

4. Output Current (Iout):

   • The typical output current is 200mA, with a maximum of 300mA. Do not exceed the maximum output current to avoid overheating and potential damage.

5. Quiescent Current (Iq):

   • The quiescent current is very low, typically around 1.5μA, making the U1660G suitable for low-power applications.

6. Dropout Voltage (Vdo):

   • The dropout voltage is typically 0.4V, which means the input voltage should be at least 0.4V higher than the output voltage to maintain regulation.

7. Load Regulation (ΔVL/ΔIL):

   • The load regulation is very good, with a typical value of 0.01% per mA. This ensures stable output voltage even under varying load conditions.

8. Line Regulation (ΔVL/ΔVI):

   • The line regulation is also excellent, with a typical value of 0.01% per V. This helps maintain a stable output voltage despite changes in the input voltage.

9. Ripple Rejection (RR):

   • The ripple rejection is high, typically 70dB at 120Hz, which helps filter out noise from the input power supply.

10. Thermal Shutdown (TSD):

    • The device has built-in thermal protection that activates at approximately 160°C. If the temperature exceeds this threshold, the device will shut down to prevent damage.

11. Short-Circuit Current (Isc):

    • The short-circuit current is limited to protect the device. It typically does not exceed 350mA but can go up to 500mA in extreme cases. Always use appropriate circuit protection to avoid short circuits.

12. Mounting and Handling:

    • Handle the device with care to avoid static damage. Follow proper soldering techniques and ensure the device is securely mounted on the PCB.

13. Application Notes:

    • For optimal performance, use bypass capacitors close to the input and output pins. A 10μF ceramic capacitor is recommended for both input and output.

By following these parameters and instructions, you can ensure reliable and efficient operation of the U1660G in your application.
