Technical Terms
*1. C
*2. In addition to a tantalum capacitor, a ceramic capacitor of 0.47 μF or more can be used in C
The low dropout voltage regulator is a voltage regulator featuring a low dropout voltage characteristic due
to its internal low ON-resistance characteristic transistors.
ESR is the abbreviation for Equivalent Series Resistance. The low ESR output capacitor (C
used in the S-814 Series.
The accuracy of the output voltage is ensured at ±2.0 % under the specified conditions

*1. The condition differs depending upon each product.
Caution If you change the above conditions, the output voltage value may vary out of the
Indicate the input voltage dependencies of output voltage. That is, the value shows how much the output
voltage changes due to a change in the input voltage with the output current remained unchanged.
