正确答案

稳压器的工作指标是指稳压器能够正常工作的工作区域,以及保证正常工作所必须的工作条件,这些工作参数取决于构成稳压器的元件性能。
(1)输出电压范围:符合稳压器工作条件情况下,稳压器能够正常工作的输出电压范围,该指标的上限是由最大输入电压和最小输入-输出电压差所规定,而其下限由稳压器内部的基准电压值决定。
(2)最大输入-输出电压差:该指标表征在保证稳压器正常工作条件下稳压器所允许的最大输入-输出之间的电压差值,其值主要取决于于稳压器内部调整晶体管的耐压指标。
(3)最小输入-输出电压差:该指标表征在保证稳压器正常工作条件下,稳压器所需的最小输入-输出之间的电压差值。
(4)输出负载电流范围:输出负载电流范围又称为输出电流范围,在这一电流范围内,稳压器应能保证符合指标规范征所给出的指标。
