LOW DROPOUT CMOS VOLTAGE REGULATOR
S-818 Series
The S-818 Series is a positive voltage regulator
developed by CMOS technology and 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 shutdown 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.
