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-89-3 and
the SOT-89-5 packages are recommended to use for
configuring portable devices and large output current
applications, respectively.

Built-in short-circuit protection
•
Low ESR capacitor, e.g. a ceramic capacitor of 0.47
µF
or more, can be used as the output capacitor.
