VOUT = 1.25V*(1+R2/R1)

For Adjustable Version

Notes:

4. Dropout voltage is 250mV when TA = +25oC. In order to obtain a normal output voltage, VOUT+0.25V is the minimum input voltage which will result a low

PSRR, imposing a bad influence on system. Therefore, the recommended input voltage is VOUT+1V to 13.2V. For AP2210-3.0 version, its input voltage

can be set from 4V (VOUT+1V) to 13.2V.
