Instructions for Use:
- Input Voltage Range: Ensure the input voltage is within the specified range of 2.7V to 5.5V. Exceeding this range can damage the device.
- Output Voltage: The device provides a fixed output voltage of 3.3V. This is suitable for powering various low-voltage circuits.
- Output Current: The device can supply up to 300mA continuously. For higher current requirements, consider using a different regulator.
- Quiescent Current: The quiescent current is very low at 1.2μA, making it suitable for battery-powered applications.
- Dropout Voltage: The dropout voltage is 300mV at 300mA. This means the input voltage must be at least 3.6V to maintain the 3.3V output.
- Load Regulation: The load regulation is 1.5%, ensuring that the output voltage remains stable over the load range from 0mA to 300mA.
- Line Regulation: The line regulation is 0.01% per volt, indicating excellent stability of the output voltage with changes in input voltage.
- PSRR (Power Supply Rejection Ratio): The PSRR is 60dB at 1kHz, which helps in filtering out noise from the input power supply.
- Operating Temperature: The device operates reliably between -40°C and 85°C. Avoid operating outside this range to prevent damage or reduced performance.
- Storage Temperature: Store the device in an environment where the temperature ranges from -65°C to 150°C.
Layout Considerations:
- Input Capacitor: Place a 1μF ceramic capacitor as close as possible to the input pin to ensure stability.
- Output Capacitor: A 1μF ceramic capacitor should be placed close to the output pin to filter out any ripple and noise.
- Ground Plane: Use a ground plane to minimize noise and improve thermal performance.
Safety Precautions:
- Overvoltage Protection: Do not apply more than 5.5V to the input to avoid damaging the device.
- Thermal Management: If the device is expected to operate near its maximum current, ensure adequate heat dissipation to prevent overheating.
- Reverse Polarity Protection: Ensure that the input polarity is correct to avoid damage to the device.
