LDO TPS7601-EP Vref value appears erroneous in Datasheet Ver. A ref. SLVSA53 not 1.127 V as stated but 1.224 V



The output voltage computations give erroneous values when using the Datasheet ver. A ref. SLVSA53 Dec 2009 which stipulates, page 8,  Vref = 1.127 V.

The real value measured at the feedback pin is 1.224 V which is the Vref value stipulated in Family Datasheet Ver. E ref. SLVS203E - May 2001.

 

Can Texas Instrument confirm this error, please?

Because this part is used for Down-Hole Drilling - the output voltage must be exactly known and verified.

 

Also, only Vref typical is specified in the application section but is not present in the electrical table or elsewhere - which is surprising.
