Technical Terms
1. 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.
Caution 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 (
VOUT1, VOUT2)
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 (
VOUT3)
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.
5. Dropout voltage (Vdrop)
This parameter indicates the difference between the input voltage (VIN1) and the output voltage when
output voltage falls to 98 % of VOUT(E) by gradually decreasing the input voltage (VIN).
Vdrop = VIN1-[VOUT(E) × 0.98]
