(Com- pared with conventional Sanken devices) • Built-in foldback-overcurrent and thermal protection circuits • Output ON/OFF available (Circuit current at output OFF: 200 µA max) • Soft start available by ON/OFF pin Conditions Conditions When mounted on glass-epoxy board 40 × 40 mm (copper area 100%) When mounted on glass-epoxy board 40 × 40 mm (copper area 100%) *: Limited by thermal protection circuit Unit V A °C °C *: Limited by Ta–PD characteristics *: Pin 5 is the ON/OFF pin. Soft start at power on can be performed with a capacitor connected to this pin. The output can also be turned ON/OFF with this pin. The output is stopped by setting the voltage of this pin to VSSL or lower. ON/OFF-pin voltage can be changed with an open-collector drive circuit of a transistor. When using both the soft-start and ON/OFF functions together, the discharge current from C3 flows into the ON/OFF control transistor. Therefore, limit the current securely to protect the transistor if C3 capacitance is large. The ON/OFF pin is pulled up to the power supply in the IC, so applying the external voltage is prohibited.
