Instructions for BD9397EFV

1. Input Voltage (VIN):

   • Ensure the input voltage is within the range of 2.5V to 5.5V.

2. Output Voltage (VOUT):

   • The output voltage can be set between 1.8V and 3.3V. Adjust using external resistors if necessary.

3. Operating and Storage Temperature:

   • Operate the device within -40°C to 85°C. Store it between -65°C and 150°C.

4. Quiescent Current (IQ):

   • Monitor the quiescent current which typically stays around 90μA at VIN = 5V and VOUT = 3.3V.

5. Dropout Voltage (VDROPOUT):

   • For a load current of 500mA, expect a dropout voltage around 300mV.

6. Load Regulation:

   • When the load current changes from 0mA to 500mA, the output voltage change should not exceed 1%.

7. Line Regulation:

   • With input voltage varying from 2.5V to 5.5V, the output voltage change should be less than 0.5%.

8. Power Supply Rejection Ratio (PSRR):

   • At a frequency of 1kHz, the PSRR is typically 60dB.
