(2) Apply voltage simultaneously to V

(3) Since the amplifiers do not have current limit protection such as an external NPN transistor, provide this protection in each
application.

Thermal Design Notes
(1) In the LA5612, the junction temperature (Tj) at which thermal shutdown is activated is approximately equal to 130°C.
(2) Consequently, the operating range of REG1, REG2 and REG3 with the thermal shutdown function is restricted by the thermal
shutdown characteristics (typical value) shown in the figure below.
(3) The thermal shutdown characteristics vary ±20°C or so. Since thermal shutdown is liable to occur with inadequate heat
dissipation, sufficient consideration must be given to the heat dissipation design.
