描述 Description

The TC1107 is a fixed output, high accuracy (typically ±0.5%) CMOS upgrade for older (bipolar) low dropout regulators. Total supply current is typically 50μA at full load (20 to 60 times lower than in bipolar regulators). TC1107 key features include ultra low noise operation (plus optional Bypass input); very low dropout voltage (typically 240 mV at full load), and fast response to step changes in load. Supply current is reduced to 0.05 μA (typical) and VOUT falls to zero when the shutdown input is low. The TC1107 incorporates both over-temperature and over-current protection. The TC1107 is stable with an output capacitor of only 1μF and has a maximum output current of 300 mA.

簡介

TC1107屬于集成電路（IC）的線性+開關穩(wěn)壓器。由制造生產(chǎn)的TC1107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換為熱量。對于大多數(shù)應用而言，雖然這種穩(wěn)壓器的效率低于開關模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應用。
