TC1017-2.8VCT集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TC1017-2.8VCT属于集成电路（IC）的线性+开关稳压器。由微芯科技股份有限公司制造生产的TC1017-2.8VCT稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。

General Description

The TC1017 is a high-accuracy (typically ±0.5) CMOS upgrade for bipolar low dropout regulators. It is offered in a SC-70 or SOT-23 package. The SC-70 package represents a 50 reduced footprint versus the popular SOT-23 package.

Developed specifically for battery-powered systems, the TC1017’s CMOS construction consumes only 53 µA typical supply current over the entire 150 mA operating load range. This can be as much as 60 times less than the quiescent operating current consumed by bipolar LDOs.
