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 (ΔV
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
