AN-1824 FlexCap Technology Simplifies LDO Design (Rev. A)
PDF, 79 Kb, 修订版: A, 档案已发布: Apr 24, 2013
The low dropout (LDO) voltage regulator brings the advantage of power savings to system design byreducing the voltage required to maintain output regulation. However, the traditional LDO has alwaysbrought with it the disadvantage of placing tight restrictions on the equivalent series resistance (ESR) ofthe output capacitor in order to keep the regulator stable. This requirement has been elim
