NOTE3: 100% production test at +25°C. Specifications over the temperature range are guaranteed by design and characterization.
NOTE4: The required minimum input operating voltage is equal to VOUT + VDROP, and if VOUT + VDROP < 2.5V, the required minimum input
operating voltage must be set to 2.5V. VOUT is the normal output voltage, e.g. VOUT = 2.8V for 2.8V fixed output version.
NOTE5: Line regulation is calculated by ∆VLINE = [(VOUT1 - VOUT2)/ (∆VDD x VOUT)] x 100
Where VOUT1 is the output voltage when VDD1 = 6.0V, and VOUT2 is the output voltage when VDD2 = max (VOUT + 0.5V, 2.5V).
∆VDD = VDD1 - VDD2
.
NOTE6: Load regulation is calculated by ∆VLOAD = VOUT1 - VOUT2
Where VOUT1 is the output voltage when IOUT1=1mA, and VOUT2 is the output voltage when IOUT2 = 1.0A.
NOTE7: The temperature coefficient is calculated by TCVOUT = ∆VOUT/ (∆T x VOUT
