Usage Notes
(1) Apply voltages to the voltage input pins on condition that V

(2) Supply the voltages simultaneously to V

2. Do not use the LA5611 with voltage applied to only one of these pins.
(3) Since the control circuit of regulator 1 does not have current limit protection of such as an external NPN transistor, provide
this protection in each application.

Thermal Design Notes
(1) In the LA5611, the junction temperature (Tj) at which thermal shutdown is activated is approximately equal to 130°C.
(2) Consequently, the operating temperature 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.
