Output capacitors (CL) Output capacitors are generally used to stabilize regulation operation and to improve transient response characteristics. But the S-812C series can provide stable operation without output capacitors. Capacitors are used only to improve transient response characteristics. Output capacitors can hence be removed in applications in which transient response can be negligible. When an output capacitor is used, a low ESR (Equivalent Series Resistance) capacitor like ceramic capacitor can also be used. 2. Output voltage (VOUT) The accuracy of the output voltage is ± 2.0% guaranteed under the specified conditions for input voltage, which differs depending upon the product items, output current, and temperature. Note: If the above conditions change, the output voltage value may vary and go out of the accuracy range of the output voltage. See the electrical characteristics and characteristics data for details. 3. Line regulations 1 and 2 ( ∆V OUT1, ∆V OUT2) These parameters indicate the input voltage dependence on the output voltage. That is, the values show how much the output voltage changes due to a change in the input voltage with the output current remained unchanged. 4. Load regulation ( ∆V OUT3) This parameter indicates the output current dependence on the output voltage. That is, the value shows how much the output voltage changes due to a change in the output current with the input voltage remained unchanged. In addition to a tantalum capacitor, a ceramic capacitor can be used for CL. See terms below. CIN is a capacitor used to stabilize input. |
