Novel LDO characteristic characterization method

The invention discloses a characteristic characterization method of an anti-radiation low dropout regulator (hereinafter referred to as LDO) for a spacecraft. According to the method, the radiation-proof LDO for the spacecraft is used as a research object, and a characterization process and method for covering the absolute maximum rated value, the static parameter, the dynamic parameter, the application characteristic parameter, the characteristic curve, the radiation-proof characteristic, the reliability index, the boundary dimension and other characteristics are established. The characterization method can be effectively applied to the development, identification and inspection, application verification, engineering application and other stages of newly developed LDO (Low Dropout Regulator). 本发明公开了一种航天器用抗辐照低压差线性稳压器(以下简称LDO)特性表征方法。本发明以航天器用抗辐照LDO为研究对象，建立了覆盖绝对最大额定值、静态参数、动态参数、应用特性参数、特性曲线、抗辐射特性、可靠性指标、外形尺寸等特性的表征流程及方法，该表征方法就成可有效应用于新研制的LDO的研制、鉴定检验、应用验证以及工程应用等阶段。
