The adjustable version of the TLV1117 takes a 2.7-V to 15-V input. The voltage VREF refers to the voltage between the output and the ADJUST pin, typically 1.25 V. The VREF voltage causes a current to flow across R1, which is the same current that flows across R2 (minus the negligible 50-µA IADJ). Therefore, R2 can be adjusted to create a larger voltage drop from GND and set the output voltage. The output voltage equation is described in the Detailed Design Procedure section.
