Instructions

1. Power Supply Connection:

   • Connect the input voltage to the VIN pin.
   • Ensure the input voltage is within the specified range (2.7V to 5.5V).

2. Output Configuration:

   • Connect the load to the VOUT1 and VOUT2 pins.
   • The output voltages are fixed at 1.8V for VOUT1 and 3.3V for VOUT2.

3. Enable Control:

   • Use the EN pin to control the operation of the regulator.
   • Apply a logic high (≥1.8V) to the EN pin to enable the regulator.
   • Apply a logic low (≤0.4V) to the EN pin to disable the regulator.

4. Ground Connection:

   • Connect the GND pin to the system ground.

5. Thermal Considerations:

   • Ensure adequate heat dissipation if operating near the maximum output current.
   • Use a heatsink or PCB copper area to improve thermal performance.

6. Capacitor Selection:

   • Place a 1μF ceramic capacitor close to the VIN pin to stabilize the input.
   • Place a 1μF ceramic capacitor close to each VOUT pin to stabilize the output.

7. PCB Layout:

   • Keep the traces from the VIN and VOUT pins short and wide to minimize inductance.
   • Ensure proper grounding and decoupling to reduce noise and improve stability.

8. Protection:

   • The IP2312 includes built-in overcurrent and thermal shutdown protection.
   • Do not exceed the maximum ratings to avoid damage to the device.

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 device.
