Hi,
I was looking for an small LDO for our application,
Vin=24V,
Vout=5V,
I<100mA
So I found UA78M05CKVURG3. I am now testing it without any caps.
1. I use normal resistors 50 ohm as the load. The output current is fine at the beginning. But when the IC gets hotter, the output voltage drops. But as I calculated according to the datasheet, the temperature should be fine.
2. I use one electronics load as the output load. I got 5V output when there is no load. But when I turn up the loading current, the output voltage drops as well, a lot. 100mA will make the voltage 4.1V
3. No matter in which condition above, the voltage will drop if I measure the output by one normal multimeter.
I don't know if you have any explanations for those.
Thanks
