The ADP 7157 is being used to create a 2 V output. The problem that arises is that Vref is around 2.9V which should be 1.2V. The output voltage is also seen to be 0.5V. The potential divider is working fine as the REF_SENSE voltage is 1.74 V for resistors R1 = 20k and R2 = 30k. The supplies to Vin and EN are 3V each.
