SA57026 Description
The SA57026 has an extremely precise fixed output with a typical accuracy of ±2%. It is designed to provide very low dropout and low noise in CD-ROM drives, battery-operated systems, and portable puters applications. This regulator consists of an internal voltage reference, an error amplifier, a driver with current limiter, and a thermal shut-down mechanism.
