The S-814 Series is a low dropout voltage, high output voltage accuracy and low current consumption positive
voltage regulator developed utilizing CMOS technology.
Built-in low ON-resistance transistors provide low dropout voltage and large output current. The ON/OFF circuit
ensures long battery life.
Various types of output capacitors can be used in the S-814 Series compared with the past CMOS voltage
regulators. (i.e., Small ceramic capacitors can also be used in the S-814 Series.)
The SOT-23-5 miniaturized package and the SOT-89-5 packages are recommended to use for configuring
portable devices and large output current applications, respectively.
