LTC1261L 开关电容器稳压负输出转换器
LTC®1261L 是一款开关电容器电压负输出转换器，专为采用单个正电源提供一个稳定的负电压而设计。LTC1261L 依靠单个 2.7V 至 5.25V 电源运作，并提供一个 -1.23V 至 -5V 的可调输出电压。LTC1261L-4 / LTC1261L-4.5 分别需要单个 4.5V 至 5.25V 电源并提供一个 -4V 至 -4.5V 的固定输出电压。需要三个外部电容器：一个 0.1μF 跨接电容器、一个输入旁路电容器和一个输出旁路电容器。ADJ (COMP) 上的一个任选的补偿电容器可用于降低输出电压纹波。
LTC1261L 的每种版本都将提供高达 20mA 的输出电流和 ±4.5% 的保证输出调节准确度。LTC1261L 包括一个漏极开路 REG 输出，当输出电压处于设定值的 5% 以内时，该输出将被拉至低电平。静态电流在工作时通常为 650μA，而停机时为 5μA。
LTC1261L 采用 8 引脚 MSOP 和 SO 封装。
