- AN-1482 LDO Regulator Stability Using Ceramic Output Capacitors (Rev. A)PDF, 169 Kb, 修订版: A, 档案已发布: Apr 25, 2013
Ultra-low ESR capacitors such as ceramics are highly desirable because they can support fast-changingload transients and also bypass very high frequency noise coming from switching converter powersources which a linear regulator can not reject. However using ultra-low ESR capacitors on the output ofan LDO regulator requires that specific design changes be implemented to ensure loop stabili
