Input Voltage (VIN):
- Ensure the input voltage is within the range of 2.5V to 5.5V.
Output Voltage (VOUT):
- The output voltage can be set between 1.8V and 3.3V. Adjust using external resistors if necessary.
Operating and Storage Temperature:
- Operate the device within -40°C to 85°C. Store it between -65°C and 150°C.
Quiescent Current (IQ):
- Monitor the quiescent current which typically stays around 90μA at VIN = 5V and VOUT = 3.3V.
Dropout Voltage (VDROPOUT):
- For a load current of 500mA, expect a dropout voltage around 300mV.
Load Regulation:
- When the load current changes from 0mA to 500mA, the output voltage change should not exceed 1%.
Line Regulation:
- With input voltage varying from 2.5V to 5.5V, the output voltage change should be less than 0.5%.
Power Supply Rejection Ratio (PSRR):
- At a frequency of 1kHz, the PSRR is typically 60dB.
