Instructions for MAX803SQ293D3T1G
Power Supply Connection: Connect the input voltage (V_IN) within the range of 2.7V to 5.5V. Ensure that the power supply is stable and free from excessive noise.
Output Configuration: The device provides a fixed output voltage of 3.3V. No external components are required for setting the output voltage.
Quiescent Current Management: The quiescent current is very low at 10μA under no-load conditions. This helps in minimizing power consumption in battery-operated devices.
Thermal Considerations: Operate the device within the junction temperature range of -40°C to +85°C. For storage, ensure temperatures do not exceed -40°C to +125°C.
Load Regulation: The load regulation is maintained at 2%, ensuring minimal change in output voltage as the load current varies from 0mA to 100mA.
Line Regulation: The line regulation is excellent at 0.1%, maintaining output stability over the entire input voltage range.
Power Supply Rejection Ratio (PSRR): The device offers a high PSRR of 60dB at 120Hz, effectively rejecting fluctuations in the input voltage.
Capacitor Requirements: Use appropriate input and output capacitors to stabilize the voltage and reduce ripple. Typical values are 1μF ceramic capacitors for both input and output.
PCB Layout Recommendations: Place the input and output capacitors as close as possible to the device's pins. Ensure a solid ground plane to enhance thermal performance and reduce electromagnetic interference (EMI).
Handling Precautions: Handle the device with care to avoid damage from electrostatic discharge (ESD). Follow standard ESD handling procedures.
