NCP1117 系列为低漏 (LDO) 正向线性电压稳压器，能够在较大温度范围内提供超过 1.0 A 的输出电流，800 mA 时的最大漏极电压为 1.2 V。此系列包括八个固定输出电压：1.5 V、1.8 V、2.0 V、2.5 V、2.85 V、3.3 V、5.0 V 和 12 V，对于保持调节没有最低负载要求。还包括可调节输出版本，可使用两个外部电阻编程为 1.25 V 至 18.8 V。片上微调可将参考/输出电压调至 +/- 1.0% 准确度范围内。内部保护功能包括输出电流限制、安全运行区域补偿和高温关断。NCP1117 系列可在高达 20 V 输入下运行。此类器件采用 SOT223 和 DPAK 封装。
