Instructions for Use:

1. Power Supply Connection:

   • Connect the input voltage (VIN) to the power supply within the range of 2.7V to 5.5V.
   • Ensure the output voltage (VOUT) is set to 3.3V.

2. Shutdown Function:

   • To enable the shutdown mode, connect the SHDN pin to ground (0V). The device will enter a low-power state with a typical shutdown current of 0.1 μA.
   • To resume normal operation, connect the SHDN pin to the input voltage (VIN).

3. Load Regulation:

   • The load regulation is typically 1% when the load current (IOUT) varies from 0 to 300mA at an input voltage of 5V.

4. Line Regulation:

   • The line regulation is typically 0.1% when the input voltage (VIN) varies from 2.7V to 5.5V at a load current (IOUT) of 0mA.

5. Dropout Voltage:

   • The dropout voltage is typically 0.3V when the load current (IOUT) is 300mA and the input voltage (VIN) is 3.6V.

6. Output Current:

   • The maximum continuous output current (IOUT) is 300mA.

7. Temperature Considerations:

   • The operating temperature range is from -40°C to 85°C.
   • The storage temperature range is from -65°C to 150°C.

8. Capacitors:

   • Use appropriate input and output capacitors to ensure stability and filter noise. Typical values are 1 μF for both input and output capacitors.

9. PCB Layout:

   • Place the SGM4581YTS16 close to the load to minimize trace resistance and inductance.
   • Ensure proper heat dissipation if operating near the maximum output current or in high ambient temperatures.

10. Safety Precautions:

    • Do not exceed the maximum ratings specified in the table.
    • Use appropriate circuit protection devices (e.g., fuses, diodes) to prevent damage from overvoltage, reverse polarity, or short circuits.
