Description
The CS403 is a linear regulator specially designed as a post regulator. The CS403 provides low noise, low drift, and high accuracy to improve the performance of a switching power supply. It is ideal for applications requiring a highly efficient and accurate linear regulator. The active RESET makes the device particularly well suited to supply microprocessor based systems. The PNP-NPN output stage assures a low dropout voltage without requiring excessive supply current. Its features include low dropout (1V typically) and low supply drain (4mA typical with IOUT = 500mA).
