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.

簡介

TC1300屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的TC1300穩(wěn)壓器 - 線性線性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無論負載電流、輸入電壓或環(huán)境因素如何變化，這些輸出電壓通常都要保持不變。它們的工作原理要求輸入電壓維持在高于所需的輸出電壓，而且要超出某個最小量，并且在工作時會將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開關(guān)模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應(yīng)用。
