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 V_OUT+V_DROP, and if V_OUT+V_DROP<2.5V, the required

minimum input operating voltage must be set to 2.5V. V_OUTis the normal output voltage, e.g. V_OUT=2.8V for 2.8V fixed

output version.

Note 9: Load regulation is calculated by

V_LOADV_OUT1V_{OUT 2}

Where V_OUT1is the output voltage when I_OUT1=1mA, and V_OUT2is the output voltage when I_OUT2=1A.
