Instructions for Use:

1. Power Supply:

   • Ensure the supply voltage (VDD) is within the range of 2.7V to 5.5V.
   • Use appropriate decoupling capacitors (typically 0.1μF and 10μF) close to the input and output pins to stabilize the power supply.

2. Output Current:

   • The device can provide up to 100mA of continuous output current.
   • For higher currents, consider using additional external components or a different regulator.

3. Quiescent Current:

   • The quiescent current is typically 1.5μA at 5V supply voltage, ensuring low power consumption.

4. Dropout Voltage:

   • The dropout voltage is typically 0.3V at 100mA output current, making it suitable for low-voltage applications.

5. Regulation:

   • The load regulation is typically 0.05% over the output current range from 10mA to 100mA.
   • The line regulation is also typically 0.05% over the input voltage range from 2.7V to 5.5V.

6. Thermal Protection:

   • The device includes thermal shutdown protection, which activates at approximately 160°C to prevent damage from overheating.

7. Short-Circuit Protection:

   • The short-circuit current is limited to typically 200mA to protect the device from damage during short circuits.

8. Layout Considerations:

   • Place the MN1381-S as close as possible to the load to minimize trace resistance and inductance.
   • Use wide and short traces for power and ground connections to reduce parasitic effects.

9. Storage and Handling:

   • Store the device in a dry environment to prevent moisture damage.
   • Handle with care to avoid static discharge, which can damage the internal components.
