TPS7A4701-EP: error analysis

Part Number: TPS7A4701-EP

Hello Team, 

I had a question regarding the TPS7A4701 LDO. In the block diagram on pg. 12 of the datasheet are you able to provide the following information? I am performing an error analysis for the LDO used in our application.


  1. What is the voltage and tolerance of the bandgap source?
  2. What is the current into the op amp from the band gap voltage?
  3. What are the tolerances of the resistors shown in the picture?

  • Hey Michael,

    It looks like the customer is doing a tolerance analysis on their output voltage.  These values are not typically provided because they are not needed.  TI provides the tolerance in the datasheet of the output voltage, which is +/- 3.5% across the line, load and operating temperature range using the ANYOUT connections.
