There is a phenomenon that the PTH module's output voltage is shifts, At my customer.
Checking the OPEN / SHORT of the pin indicates that the ADJ pin is OPEN or the resistance value is misaligned.
Since the occurrence mechanism and the cause of occurrence are investigating , please tell me only about the phenomenon.
<Question>
· I think that the impedance fluctuation of the ADJ pin influences the output voltage, but is this consideration correct?
· If there is a block diagram (may be a simplified diagram) of the internal circuit, please send.
※I would like to discuss within the company's internal based on this.
Could you help us?
