GENERAL DESCRIPTION
The SA57022-XX has an extremely precise fixed output with a
typical accuracy of
±
2%. It 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
μ
F and has a maximum output current of
500 mA. It is available in the 7-pin small outline package (SOP002).
