Description

The TC1265 is a fixed-output, high-accuracy (typically ±0.5) CMOS low dropout regulator. Designed specifically for battery-operated systems, the TC1265’s CMOS construction eliminates wasted ground current, significantly extending battery life. Total supply current is typically 80 µA at full load (20 to 60 times lower than in bipolar regulators).

TC1265-1.8VOA属于集成电路（IC） > 线性 + 开关稳压器。微芯科技股份有限公司制造生产的TC1265-1.8VOA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。
