TPS7A52-Q1: Capacitance at BIAS Pin

Part Number: TPS7A52-Q1


I am using TPS7A5201-Q1 LDOs in my design.

  1. One LDO is used to generate 0.9V (@0.4A) from 1.2V
  2. Another LDO is used to generate 1.2V (@1A) from 1.5V.

I am connecting 5V supply to the BIAS pin of both the regulators. As per datasheet, minimum capacitance at the BIAS pin should be 10uF.

Is it OK to combine both the capacitors and connect only one 22uF for both the bias pins of 2 LDOs (Doing this because there is space constraint and I have multiple such LDOs on board)?

Or Is it strictly recommended to connect separate 10uF at BIAS pin for each IC?

Thanks in Advance.
