When Vcc is turned on it takes at least 100 ms for the internal circuit to stabilize. During this time the output signal is unstable. Please do not use the unstable signal as the output signal. Moisture-Proof Packing (1) (2) (3) To avoid moisture absorption by the resin, the product is packed in an aluminum envelope with silica gel. Since the optical characteristics of the device can be affected during soldering by vaporization resulting from prior absorption of moisture and they should therefore be stored under the following conditions: Temperature: 5°C to 30°C, Relative humidity: 70% (max), Time: 168 h (max) Baking is required if the devices have been store unopened for more than six months or if the aluminum envelope has been opened for more than 168 h. These devices are packed on tapes; hence, please avoid baking at high temperature. Recommended baking conditions: 60°C for 12 h or longer Mounting Precautions TPS853 uses a clear resin, and delicate handling is necessary for it. The characteristic change or the product might be damaged by the handling method of mounting. Please note the following and handle the product. (1) Do not apply stress to the resin at high temperature. Time until the product returns at the normal temperature after mounting of the reflow is different according to the mounting substrate and the environment. Please do not give the stress with heat remained in the product. (2) The resin part is easily scratched, so avoid friction with hard materials. (3) When installing the assembly board in equipment, ensure that this product does not come into contact with other components. (4) Please confirm the heat contraction of the substrate of the reflow mounting doesn't influence the product. The load is given to the product by mounting that the heat contraction is large on the substrate and the installation position of the substrate. Please note that the characteristic changes or the product might be damaged.
