并联-LDO稳压器是一种新的稳压器概念，它结合了一个分流和一个低掉差（LDO）稳压器。设计为一种改进的分流稳压器，以满足串行供电检测器系统的需求，它也可以用作纯LDO稳压器，用于需要线性调节的供电方案的一般应用。设计的灵活性使并联ldo稳压器成为ATLAS像素探测器升级所设想的供电方案的良好候选者。下一个ATLAS像素前端芯片FE-I4A的原型中集成了两个并联ldo稳压器，用于演示所提出的供电解决方案的可行性。
The shunt-LDO regulator is a new regulator concept which combines a shunt and a Low Drop-Out (LDO) regulator. Designed as an improved shunt regulator to match the needs of serially powered detector systems, it can also be used as a pure LDO regulator for general application in powering schemes requiring linear regulation. The flexibility of the design makes the shunt-LDO regulator a good candidate for use in the powering schemes envisaged for the upgrades of the ATLAS pixel detector. Two shunt-LDO regulators integrated in the prototype of the next ATLAS pixel front-end chip, the FE-I4A, are used to demonstrate the feasibility of the proposed powering solutions.
