Description

The SA57022-XX has an extremely precise fixed output with a typical accuracy of ±2%. SA57022-XX is designed to provide very low dropout and ultra low noise with an optional Bypass pin, and fast transient response. Supply current is reduced to zero (typical).

The SA57022-XX incorporates both over-temperature and over-current protection. The SA57022-XX is stable with an output capacitor of only 1.0 mF and has a maximum output current of 500 mA. It is available in the 7-pin small outline package (SOP002).
