ULTRA LOW CURRENT CONSUMPTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR
S-1206 Series
Technical Terms
1. Low Dropout Voltage Regulator
2. Low Equivalent Series Resistance
3. Output Voltage (V
4. Line Regulation
5. Load Regulation (∆V
6. Dropout Voltage (V
The low dropout voltage regulator is a voltage regulator whose dropout voltage is low due to its built-in low-on-
resistance transistor.
A capacitor whose equivalent series resistance (R

Caution If the above conditions change, the output voltage value may vary and exceed the accuracy range
Indicates the dependency of the output voltage on the input voltage. That is, the values show how much the output
voltage changes due to a change in the input voltage with the output current remaining unchanged.
