Instructions

1. Supply Voltage (Vcc):

   • The device operates within a supply voltage range of 1.8V to 5.5V.
   • Ensure that the input voltage is stable and within the specified range to avoid damage or malfunction.

2. Operating Temperature (Ta):

   • The device can operate from -40°C to 85°C.
   • Avoid exposing the device to temperatures outside this range to prevent performance degradation or failure.

3. Storage Temperature (Tstg):

   • The device can be stored from -65°C to 150°C.
   • Store the device in a dry and temperature-controlled environment to ensure long-term reliability.

4. Output Current (Iout):

   • The device can provide a continuous output current of up to 200mA.
   • For short pulses, the peak output current can reach up to 500mA for 10ms.

5. Quiescent Current (Iq):

   • The quiescent current is typically 1.5μA at no load and Vcc = 3.3V.
   • This low quiescent current makes the device suitable for battery-powered applications.

6. Dropout Voltage (Vdo):

   • The dropout voltage is typically 0.3V at Iout = 100mA and Vcc = 3.3V.
   • Ensure that the input voltage is at least 0.3V higher than the desired output voltage to maintain regulation.

7. Load Regulation (ΔVout/ΔIout):

   • The load regulation is typically 10mV/A over the load range of 10mA to 100mA.
   • This indicates how well the output voltage remains constant as the load changes.

8. Line Regulation (ΔVout/ΔVin):

   • The line regulation is typically 10mV/V over the input voltage range of 2.5V to 5.5V.
   • This indicates how well the output voltage remains constant as the input voltage changes.

9. Thermal Shutdown (TSD):

   • The device has thermal shutdown protection that activates at approximately 150°C.
   • This feature helps prevent damage due to excessive heat.

10. Short-Circuit Protection (SCP):

    • The device includes short-circuit protection with auto-restart functionality.
    • In the event of a short circuit, the device will automatically restart once the fault is cleared.

Additional Notes:

• PCB Layout:

  • Ensure proper PCB layout to minimize noise and improve thermal performance.
  • Use a large ground plane and place decoupling capacitors close to the device.

• Capacitors:

  • Use ceramic capacitors with low ESR for input and output filtering.
  • Typical values are 10μF for input and 10μF for output.

• Heat Dissipation:

  • If operating at high currents or in high ambient temperatures, consider using a heatsink or thermal pad to improve heat dissipation.

By following these parameters and instructions, you can ensure optimal performance and reliability of the ECN3297TF.
