Instructions for Use:

1. Power Supply Connection:

   • Connect the input voltage between VIN and GND.
   • Ensure the input voltage is within the specified range of 2.7V to 5.5V.

2. Output Configuration:

   • The MUN5113DW1T1G provides a fixed output voltage of 1.8V. No external resistors are required for voltage setting.

3. Bypass Capacitors:

   • Place a 1μF ceramic capacitor between VIN and GND close to the device for stability.
   • Place a 1μF ceramic capacitor between VOUT and GND close to the device for stability.

4. Thermal Considerations:

   • Ensure adequate heat dissipation if operating near the maximum output current, especially in high ambient temperatures.

5. Shutdown Function:

   • To place the device into shutdown mode, pull the EN pin low. This reduces the supply current to 0.01μA.

6. Layout Recommendations:

   • Keep the PCB traces short and wide to minimize parasitic inductance and resistance.
   • Ensure good grounding practices to maintain optimal performance and noise immunity.

7. Handling Precautions:

   • Handle with care as ESD-sensitive components can be damaged by static electricity.
   • Follow proper soldering techniques to avoid thermal damage during assembly.
