Power Supply IC


Series Regulators

This is a direct current stabilizing circuit used after AC/DC converters and elsewhere. It has only a few external components, and desired voltages can be generated easily. Compared to an SW power supply, it has superior noise characteristics.

Shunt Regulators

This is a standard reference voltage supply widely used for SW power supply feedback circuits and other purposes. Compared to a zener diode which is a discrete product, it has superior voltage accuracy because it controls voltage as an IC.

Switching Regulator Controller

This is a control IC for switching power supplies. It is used to control AC/DC and DC/DC converters. Compared to a series regulator, it has superior efficiency characteristics.
