Instructions for Use:
- Input Voltage (VIN): Ensure the input voltage is within the range of 2.7V to 5.5V.
- Output Voltage (VOUT): The device provides a fixed output voltage of 3.3V.
- Output Current (IOUT): The regulator can supply up to 300mA continuously.
- Quiescent Current (IQ): The quiescent current is typically 60μA at an input voltage of 5V.
- Dropout Voltage (VDROPOUT): At an output current of 100mA, the dropout voltage is typically 250mV.
- Load and Line Regulation: The load regulation is typically 0.5% over the load range from 0mA to 300mA, and the line regulation is typically 0.1% over the input voltage range from 2.7V to 5.5V.
- Power Supply Rejection Ratio (PSRR): At a frequency of 1kHz, the PSRR is typically 60dB.
- Operating Temperature: The operating junction temperature range is from -40°C to +85°C.
For optimal performance, ensure that the input voltage is sufficiently higher than the output voltage to maintain the dropout voltage margin. Place appropriate bypass capacitors near the input and output terminals to stabilize the regulator operation.
