Instructions for Use:
- Supply Voltage (VDD): Ensure the supply voltage is within the range of 1.6V to 5.5V.
- Output Voltage (VOUT): The device provides a fixed output voltage of 1.8V.
- Quiescent Current (IQ): Keep in mind that the quiescent current is typically 40μA when there is no load and VIN equals VOUT.
- Dropout Voltage: For optimal performance, ensure the dropout voltage does not exceed 230mV at a load current of 200mA.
- Load Regulation: The load regulation is typically 0.1%, ensuring stable output voltage across varying loads from 0mA to 200mA.
- Line Regulation: Maintain line regulation at 0.02% per volt change in input voltage ranging from 2.7V to 5.5V.
- PSRR (Power Supply Rejection Ratio): The device offers a typical PSRR of 70dB at a frequency of 1kHz, which helps in filtering out noise from the power supply.
- Operating Temperature: The operating junction temperature should be between -40°C and 125°C.
Ensure all connections are secure and meet the specified parameters for reliable operation.
