(1) The output current should be reduced according to an increase in the input voltage or ambient
(2) Pins 5 and 7 are no connected.
(3) No circuit is installed in the modules to protect against over output currents. Take physical safety measures
(4) A large rush current may flow in the module when the input voltage is applied or the output ON / OFF is

controlled with pin 4 without a capacitor such as C1 in application 4. Operating within the safe operation
ranges shown in Figs.12, 15, and 18.
The safe operation range is determined by the safe operation range of the internal switching transistor.
The amount of rush current depends on the output impedance of the input power supply and capacitors
connected to the module outputs. The pulse load on the internal switching transistor at the start of operation
can be reduced by using the protection circuit of application 1 or the slow start circuit of application 4.
