Instructions for CXA1585Q:
- Power Supply Connection: Connect the supply voltage (VDD) between 2.7V and 5.5V to the input pin of the CXA1585Q.
- Ground Connection: Ensure a solid ground connection is made to the GND pin.
- Output Configuration: The output voltage (VOUT) can be set within the range of 1.2V to 3.3V depending on the application requirements.
- Quiescent Current Consideration: The device operates with a low quiescent current of approximately 10μA at 5V supply, making it suitable for low-power applications.
- Thermal Management: Ensure adequate heat dissipation if operating near maximum supply voltage and load conditions.
- Load Regulation: The device maintains good load regulation of 0.2% from 0mA to 10mA load current.
- Line Regulation: Maintain line regulation of 0.1% over the supply voltage range.
- PSRR: The power supply rejection ratio is 60dB at 1kHz, providing effective noise suppression.
- Dropout Voltage: Operates efficiently with a dropout voltage of 200mV at 10mA load current.
