AN-1482 LDO Regulator Stability Using Ceramic Output Capacitors (Rev. A)
ثبت نشده
چکیده
Ultra-low ESR capacitors such as ceramics are highly desirable because they can support fast-changing load transients and also bypass very high frequency noise coming from switching converter power sources, which a linear regulator can not reject. However, using ultra-low ESR capacitors on the output of an LDO regulator requires that specific design changes be implemented to ensure loop stability.
