TPS715 feedback circuit with small resistance values

Other Parts Discussed in Thread: TPS715

Hi,

I was reading the application of the TPS715 regulator and it said for optimal performance set the divider current at 1.5uA. I am limited in space to use large resistors and noise performance. Is it possible to use smaller value resistors to achieve the same feedback and performance?

    Hi Aasrith,

    Using lower value resistors is fine.  The tradeoff is that you will consume more power.  More information can be found on page 8 of the datasheet under "Programming the TPS71501 Adjustable LDO Regulator."

    Very Respectfully,

    Ryan
