：LM2940CT(三脚）是什么器件？知道的师傅请告知，了
---------------------------------
Typical Application
00882203
*Required if regulator is located far from power supply filter.
**COUT must be at least 22 μF to maintain stability. May be increased without bound to maintain regulation during transients. Locate as close as possible
to the regulator. This capacitor must be rated over the same operating temperature range as the regulator and the ESR is critical; see curve.
