Note 1: Absolute Maximum Ratings are those values beyond which the life of a device may be impaired.
Note 2: The BL9110 is guaranteed to meet performance specifications from 0°C to 70°C. Specifications over the 40°C to
85°C operating temperature range are assured by design, characterization and correlation with statistical
process controls.

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.
Note 8: Line regulation is calculated by

Where VOUT1 is the output voltage when VDD1=6.0V, VOUT2 is the output voltage when VDD2= max (VOUT+0.5V, 2.5V).
VDD=VDD1-VDD2.
Note 9: Load regulation is calculated by VLOAD VOUT1 VOUT 2
Where VOUT1 is the output voltage when IOUT1=1mA, and VOUT2 is the output voltage when IOUT2=1.0A.
Note 10: The temperature coefficient is calculated by
