Overview - S-814 series

Low Dropout CMOS Voltage Regulator S-814 series

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.
A power-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 package are recommended to be used for configuring portable devices and large output current applications, respectively.
