Jameco 5V 1A wallwart linear PSU
Posted by AbeCollins on February 15, 2017 at 09:26:04:
I'd be curious to know what you think of that Jameco wall wart linear PSU. Dynobot seemed pretty impressed with it when he stated, "it measures 5.00v with ZERO fluctuation."
I wonder if he actually measured that 5.00v with and without a load. The specs in the datasheet for that PSU are pretty standard fare showing a variance of 5V +/- 0.3V as being within spec for the voltage output. The ripple spec (hum) under load is rated at 250mV (a full 1/4 volt), but that was measured under a 1500mA as best I can tell from the datasheet.
