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 shutdown 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.
