lower
than the minimum recommended one of 12V
(See Electrical Characteristics); in this case, by
acceptinga possible small increas in the R
DS (ON)
resistance of the power output transistors at the
lowest SupplyVoltage value, may be a good solu-
tion the one shown in Fig. 20.
THERMAL CHARACTERISTICS
Thanks to the high efficiency of this device, often
a true heatsink is not needed or it is simply ob-
tained by means of a copper side on the P.C.B.
(L6201/2).
Under heavy conditions, the L6203 needs a suit-
able cooling.
By using two squarecopper sides in a similar way
as it shown in Fig. 23, Fig. 21 indicates how to
choose the on board heatsink area when the
L6201 total power dissipation is knownsince:

Figure 22 shows the Transient Thermal Resis-
tance vs. asingle pulse time width.
Figure23 and 24 refer to the L6202.
For the Multiwatt L6203 addition information is
given by Figure25 (Thermal Resistance Junction-
Ambient vs. Total Power Dissipation) and Figure
26 (Peak Transient Thermal Resistance vs. Re-
petitivePulse Width) while Figure 27 refers tothe
single pulse Transient Thermal Resistance.
