LOW DROPOUT CMOS VOLTAGE REGULATOR _{S-818 Series}
The S-818 Series is a positive voltage regulator developed
utilizing CMOS technology featured by low dropout voltage,
high output voltage accuracy and low current consumption.
Built-in low on-resistance transistor provides low dropout
voltage and large output current. A ceramic capacitor of 2 µF
or more can be used as an output capacitor. A power-OFF
circuit ensures long battery life.
The SOT-23-5 miniaturized package and the SOT-89-5
package are recommended for configuring portable devices
and large output current applications, respectively.
