Hello,
Please check schematic here: /cfs-file/__key/communityserver-discussions-components-files/196/TPS7A33.pptx
usage condition is Vin=-5V, Vout=-2.5V
R1 and R2 were calculated with datasheet description, as R1=112.5Kohm and R2=100Kohm. But actual measurement voltage was -2.2V.
What is problem? please give your advise.
Best regards, Katsu
