Notes: 1. A capacitor with a low temperature coefficient must be used as the EN DELAY delay capacitor. 2. The VO1 and VO2 output capacitors must have values of at least 100 F and capacitors with low temperature coefficients must be used to prevent oscillation at low temperatures. 3. External noise can be suppressed and ripple rejection improved by adding capacitors between CN1 and VO1 and between CN2 and VO2.
Specifications of any and all SANYO products described or contained herein stipulate the performance, characteristics, and functions of the described products in the independent state, and are not guarantees of the performance, characteristics, and functions of the described products as mounted in the customer's products or equipment. To verify symptoms and states that cannot be evaluated in an independent device, the customer should always evaluate and test devices mounted in the customer's products or equipment. SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all semiconductor products fail with some probability. It is possible that these probabilistic failures could give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire, or that could cause damage to other property. When designing equipment, adopt safety measures so that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective circuits and error prevention circuits for safe design, redundant design, and structural design.
