Part Number: TLV760

My Customer has question.

The customer wants a PSRR value under the following conditions.

VIN=VOUT+1.5V

VOUT=15V

IOUT=10mA

Is it possible to confirm?

Hi T Kishi,

We do not currently have data for this condition. Due to the high volume of customer requests right now, please allow several weeks for us to generate this data for you.

Very Respectfully,
Ryan

Hi Ryan

Thank you for reply.

If you measure it, how should it be measured?
Could you tell me the measurement environment for PSRR graphs?

If there is a 15V output (15V+1.5V input), is there a possibility that Data will change significantly compared with the result of Figure13,

5V output (5V+1.5V input) in the data sheet?

If we know that it does not change much, we think that we can answer based on the graph in Figure 13.

Hi T Kishi,

PSRR is affected by various application specific conditions such as headroom, output voltage, and output current. Unfortunately your application conditions vary enough from the figures provided in the datasheet that the figures in the datasheet would not be a great reference for you.

Here are a couple of application notes that discuss techniques for measuring PSRR:

I was able to complete taking PSRR over your application conditions.

Very Respectfully,

Ryan

Hi Ryan

I'm really sorry, is it possible to measure Data at 100 mA load?
I am aware that it is difficult but I would like you to measure it.

Best Regard
