Note 5: 100% production test at +25°C. Specifications over the temperature range are guaranteed by design and
characterization.
Note 6: This IC includes two kinds of output voltage accuracy versions. A: ±1%, B: ±2%.
Note 7: 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.
