TC1017中文资料150mA Tiny CMOS LDO with Shutdown数据手册Microchip规格书

描述 Description

The TC1017 is a high accuracy (typically ±0.5%) CMOS upgrade for bipolar low dropout regulators. It is offered in an SC-70 package, which represents 50% reduced footprint vs. the widely used SOT-23 package.Designed specifically for battery-operated systems, the devices' CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 53µA at full load (20 to 60 times lower than in bipolar regulators!).Key features for thedevice include ultra low-noise operation, fast response to step changes in load, and very low dropout voltage, typically 285mV at full load. Supply current is reduced to 0.5µA (max) and VOUT falls to zero when the shutdown input is low. The device also incorporates over-temperature and over-current protection.The TC1017 is stable with an output capacitor of only 1µF (ceramic) and has a rated output current of 150mA.

简介

TC1017属于集成电路（IC）的线性+开关稳压器。由制造生产的TC1017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。
