Instructions for Use:
- Input Voltage Range: Ensure the input voltage is within the specified range of 1.6V to 5.5V.
- Output Voltage Setting: The output voltage can be set between 1.2V and 3.3V using external resistors or by selecting a fixed output version.
- Output Current: The device is capable of providing up to 3.0A of output current with a typical value of 2.0A.
- Quiescent Current: The quiescent current should be kept as low as possible to minimize power consumption, typically around 30μA.
- Dropout Voltage: The dropout voltage is the difference between the input and output voltages at which the regulator can no longer maintain regulation. It is typically 300mV to 500mV at full load.
- PSRR (Power Supply Rejection Ratio): The PSRR indicates the ability of the regulator to reject ripple from the input voltage. At 100Hz, it is typically 70dB.
- Line Regulation: The change in output voltage due to changes in input voltage should not exceed 0.5%.
- Load Regulation: The change in output voltage due to changes in load current should not exceed 0.5%.
- Thermal Shutdown: The device will shut down if the temperature exceeds 150°C to prevent damage.
- Operating Temperature: The device is designed to operate over a wide temperature range from -40°C to 125°C.
Layout Considerations:
- Place the input and output capacitors as close as possible to the device to minimize noise and improve stability.
- Use a good thermal design to ensure the device operates within its temperature limits, especially under high load conditions.
- Ensure the PCB layout minimizes parasitic inductance and resistance to optimize performance.
