TC2186屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由微芯科技股份有限公司制造生產(chǎn)的TC2186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(fù)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。

General Description

The TC2054, TC2055 and TC2186 are high accuracy (typically ±0.4) CMOS upgrades for older (bipolar) low dropout regulators. Designed specifically for battery-operated systems, the devices’ total supply current is typically 55 μA at full load (20 to 60 times lower than in bipolar regulators).

The TC2054, TC2055 and TC2186 are stable with a low esr ceramic output capacitor of 1 μF and have a maximum output current of 50 mA, 100 mA and 150 mA, respectively. This LDO Family also features a fast response time (60 μs typically) when released from shutdown.
