Instructions for Use
Input Voltage:
- Ensure the input voltage is within the specified range (2.7V to 5.5V) to avoid damage to the device.
- Connect the input voltage to the VIN pin.
Output Voltage:
- The ETA1611S2G provides a fixed output voltage of 3.3V. No external components are required for setting the output voltage.
Output Current:
- The maximum continuous output current is 1.1A. Ensure that the load does not exceed this limit to prevent overheating and potential damage.
Quiescent Current:
- The typical quiescent current is 20μA, which is relatively low, making the device suitable for battery-powered applications.
Dropout Voltage:
- The typical dropout voltage is 150mV at a maximum output current of 1.1A. This ensures efficient operation even when the input voltage is close to the output voltage.
Load Regulation:
- The load regulation is typically 1%, indicating that the output voltage remains stable over a wide range of load currents.
Line Regulation:
- The line regulation is typically 0.1% per volt, ensuring that the output voltage remains stable over the entire input voltage range.
Power Supply Rejection Ratio (PSRR):
- The PSRR is typically 60dB at 1kHz, providing good noise rejection and clean output voltage.
Thermal Shutdown:
- The device will automatically shut down if the junction temperature exceeds 160°C to protect against thermal damage.
Operating Temperature:
- The operating ambient temperature range is -40°C to 85°C. Ensure that the device is used within this range to maintain reliable performance.
Storage Temperature:
- The storage temperature range is -65°C to 150°C. Store the device in a dry, cool place to prevent damage.
Mounting and Handling:
- Handle the device with care to avoid static discharge and mechanical damage.
- Follow standard surface mount technology (SMT) guidelines for mounting the device on a PCB.
Capacitors:
- Use appropriate input and output capacitors to ensure stability and filter out noise. Refer to the datasheet for specific recommendations.
PCB Layout:
- Place the input and output capacitors as close as possible to the device to minimize parasitic inductance and improve performance.
By following these instructions, you can ensure optimal performance and reliability of the ETA1611S2G in your application.
