I Usage Notes
* Please avoid the short circuit to VCC , ground, or load short circuit. * Please connect the cooling fin with the GND potential. * The thermal shutdown circuit operates at about Tj = 150C. However, the thermal shutdown circuit is reset automatically if the temperature drops. * Please carefully design the heat radiation especially when you take out high power at high VCC . * Please connect only the ground of signal with the signal GND of the amplifier in the previous stage.

Request for your special attention and precautions in using the technical information and semiconductors described in this material
(1) An export permit needs to be obtained from the competent authorities of the Japanese Government if any of the products or technologies described in this material and controlled under the "Foreign Exchange and Foreign Trade Law" is to be exported or taken out of Japan. (2) The technical information described in this material is limited to showing representative characteristics and applied circuit examples of the products. It does not constitute the warranting of industrial property, the granting of relative rights, or the granting of any license. (3) The products described in this material are intended to be used for standard applications or general electronic equipment (such as office equipment, communications equipment, measuring instruments and household appliances). Consult our sales staff in advance for information on the following applications: * Special applications (such as for airplanes, aerospace, automobiles, traffic control equipment, combustion equipment, life support systems and safety devices) in which exceptional quality and reliability are required, or if the failure or malfunction of the products may directly jeopardize life or harm the human body. * Any applications other than the standard applications intended. (4) The products and product specifications described in this material are subject to change without notice for reasons of modification and/or improvement. At the final stage of your design, purchasing, or use of the products, therefore, ask for the most up-to-date Product Standards in advance to make sure that the latest specifications satisfy your requirements.
