NOTE3: Production test at +25°C. Specifications over the temperature range are guaranteed by design and characterization.
NOTE4: Line regulation is calculated by ΔVLINE= [(VOUT1-VOUT2)/(ΔVINxVOUT(normal))]x100
Where VOUT1 is the output voltage when VIN=5.5V, and VOUT2 is the output voltage when VIN=4.3V, ΔVIN=1.2V .VOUT(normal)=3.3V
NOTE5: Load regulation is calculated by ΔVLOAD= VOUT1-VOUT2
Where VOUT1 is the output voltage when IOUT=1mA, and VOUT2 is the output voltage when IOUT=300mA.
NOTE6: The temperature coefficient is calculated by TCVOUT=ΔVOUT /ΔTxVOUT
