TC1300中文资料300mA CMOS LDO with Microcontroller Reset数据手册Microchip规格书

描述 Description

The TC1300 combines a Low Dropout Regulator and a Microprocessor Reset Monitor in a space-saving 8-Pin MSOP package. Total supply current is 80 µA (typical), 20 to 60 times lower than in bipolar regulators. The TC1300 has an extremely precise output with a typical accuracy of ±0.5%. Other key features include ultra low noise operation, very low dropout voltage and internal feed-forward compensation for fast response to stepchanges in load. The TC1300 incorporates both over-temperature and over-current protection. When the shutdown control (SHDN) is low, the regulator output voltage falls to zero, RESET output remains valid and supply current is reduced to 30 µA (typical). The TC1300 is stable with an output capacitor of only 1 µF and has a maximum output current of 300 mA. An active low RESET is asserted when the detected voltage (VDET) falls below the reset voltage threshold. The RESET output remains low for 300 msec (typical) after VDET rises above reset threshold. The TC1300 also has a fast wake up response time (10 µsec typically) when released from shutdown.

简介

TC1300属于集成电路（IC）的线性+开关稳压器。由制造生产的TC1300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。
