Protection Circuit
(1)Over-current protection circuit
When the maximum rating current or more is rushed, it controls the
current ability and protects the IC from destruction.

(2) Thermal shutdown circuit
When the chip temperature of IC exceeds the setting temperature, the IC goes
OFF, and it controls the IC not to be destroyed by the heat generation.
It can be restored by being lowered the chip temperature of IC below the
setting temperature.
(3) Safety operation area control circuit
It controls the output current in inverse proportion ratio to voltage difference
(input-output).
When voltage difference becomes bigger, the IC will be destroyed in rush current.
It protects the IC by controlling the current ability according to the voltage level.
