The molded plastic portion of this unit, measuring 5.5 mm
(L) by 6.8 mm (W) by 2.5 mm (T), is more compact
compared to its equivalent TO-220.
The GND fin extends directly out of the main body, and can
be soldered directly to the ceramic circuit board for
significant increase in power dissipation.
To obtain high reliability in the heat sink design of the
regulator IC, it is generally required to derate more than
20% of maximum junction temperature (T
Further, full consideration should be given to the
installation of IC on a heat sink.
