Decreasing the output voltage
... The input voltage, VIN, powers the regulator and can be supplied with voltages up to 38V. The effective lower limit of VIN is VOUT plus the regulator’s dropout voltage, which varies approximately linearly with the load from around 500 mV to a little over a volt (see below for graphs of dropout volta ...

2A Sink/Source Bus Termination EUP7171 DESCRIPTION
... REFEN is an external reference input for the EUP7171. For SSTL-2 applications, VREF should be a 1.25V that the regulator can trace for termination voltage VOUT. It is recommended to place a 0.01uF to 0.1uF bypass capacitor at close to the VREF pin. An additional function included in the VREF is an a ...
