LM317T allows special power supply needs

"A very useful device for special power supply needs. Internal protection makes this voltage regulator almost bullet-proof. The pin-out diagram on [...] packaging can be confusing, due to the dotted-line reference to the back of the unit; it isn't clear as to whether the diagram refers to the front view or the back view. Try dowloading a datasheet from the manufacturer. The one that I used was made by ST Microele..." Read Full Review »

Product Good, Failed on packaging

"Showing a pic on the back that implies to me a view of the back not the front, saying face-view would help even with the drawing looking as a back or drawing the view in 3D would help, but as it is there labeling sucks, other wise it is a good product! Recomend the product yes, but only if it has a data sheet online with the product, currently unavailable. Lee..." Read Full Review »

"This is a must have for your parts drawer. If you need ANY voltage between 1.5 and 37 volts at up to 1.5 amps, this will do it for you.

The pinout and the schematic on the back of the blister package is fairly useless. The drawing is oddly presented with the back side up, the dotted lines make it …" Read Full Review »

"Too much unnecessary fuss about the case orientation. Since there is a transverse line visible (which is the top of the black chip) roughly halfway between the top and the pins, the view must be of the front. The back side of the case is flush, no such line would display there.

Quite easy to cr …" Read Full Review »
