Part Number: TLV61224

Tool/software:

I have a issue with the TLV61224 creating vout = 5,9v on vin = 2,8v. According to specification this is not possible...

What can cause this and how can I solve it?

Hi Joris,

I'm afraid the device could only support 5,5V output, while 5.9V is out of the range.

Are we talking about the same device?

So Joris, did you observe Vout =5.9V? The target should be 3V. Could you show some waveforms?

Hello Nini,

Yes, this is the whole issue. It should not be possible to get a Vout above 3v according to the datasheet.

Unfortunately I do not have direct access to a oscilloscope/data logger. Where should I check the waveforms when I can gain access to a oscilloscope?

Could you borrow one? because it's hard to detect the issue without any waveform.
