Typical Application (Continued)
Note 7: Dropout voltage is 250mV when T
A
=25 o C. In order to obtain a normal output voltage, V
OUT
+0.25V is the minimum
input voltage which will results a low PSRR, imposing a bad influence on system. Therefore, the recommended input voltage
is V
OUT
+1V to 13.2V. For AP2210-3.0 version, its input voltage can be set from 4V(V
OUT
+1V) to 13.2V.
For Adjustable Version
V
OUT
=1.25V*(1+R2/R1)
