i was wondering, why didn't the footprint SOT-223 isn't explained in this Datasheet?
DPAK is explained, but what about the rest of the packages?
In what way do you mean? I see all 4 packages described there, both the pinouts and PCB layout...
Hi
The 6th sheet, 6/44 shows pinouts for SOT-223
29th sheet, 29/44 has physical dimensions.

i'm talking about something like this:
Well, I withdraw my comment then. I thought I saw that, but nope, sure enough it isn't there. But any SOT-223 footprint will work as it is a standard. Odd that ST didn't include the other 3 (their datasheets are usually very thorough in my experience), but put the DPAK one in twice... There is this note on page 43:
06-Dec-2006 -- Revision 20 -- DPAK mechanical data updated and added footprint data
Guess none of them were on there at one time.

maybe SOT-223 isn't in the datasheet because they expect the consumers to google it for meassurements....?
ST datasheets are rather sketchy in my experience...

Now that I think back, there is a glaring detail missing on every single one of their digital accelerometer datasheets...so you may be right...
While on the subject I think my favorite are LTC datasheets, as exemplified by http://cds.linear.com/docs/en/datasheet/3780ff.pdf,
seems very clear and well organised and thorough, worked examples of choosing components,
suggested PCB layout and very clear circuit diagrams.
Hi,
The pad pattern is supplied by your PCB editor.
The pin allocation and package type are all that I'd expect from a component supplier
