16 V INPUT, 75 mA VOLTAGE REGULATOR
S-812C Series
Rev.7.0_01

Explanation of Terms
1. Output capacitor (CL)
Generally in voltage regulator, output capacitor is used to stabilize regulation and to improve the
characteristics of transient response. The S-812C Series operates stably without output capacitor CL.
Thus the output capacitor CL is used only for improvement of the transient response. In the applications
that users will use the S-812C Series, and they are not cautious about the transient response, it is
possible to omit an output capacitor. If using an output capacitor for this IC, users are able to use devices
such as ceramic capacitor which has small ESR (Equivalent Series Resistance).
2. Output voltage (VOUT)
The accuracy of the output voltage
 2.0% is assured 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. Refer to " Electrical Characteristics" and "
Characteristics (Typical Data)" for details.
3. Line regulations 1 and 2 (
VOUT1, VOUT2)
Indicate the dependency of the output voltage against the input voltage. That is, the value shows how
much the output voltage changes due to a change in the input voltage after fixing output current constant.
4. Load regulation (
VOUT3)
Indicates the dependency of the output voltage against the output current. That is, the value shows how
much the output voltage changes due to a change in the output current after fixing output current
constant.
5. Dropout voltage (Vdrop)
Indicates the difference between input voltage (VIN1) and the output voltage when; decreasing input
voltage (VIN) gradually until the output voltage has dropped out to the value of 98% of the actual output
voltage (VOUT(E)).
Vdrop = VIN1  (VOUT(E)  0.98)
