描述 Description

The TC1301A/B combines two Low Drop Out (LDO) regulators and a microcontroller RESET function while the TC1302A/B is purely a dual LDO. Both parts are available in single 8-pin MSOP or DFN package. The TC1301A/B & TC1302A/B features low dropout voltages as low as 104mV @ 300mA, low quiescent current consumption at 116 μA typical and a voltage output accuracy of +/- 0.5%. Several fixed output voltage and detector voltage combinations are available. A reference bypass pin is available for TC1301A/B to further reduce output noise and improve the power supply rejection ratio of both LDOs. The TC1301A/B & TC1302A/B is stable over all line and load conditions with a minimum of 1 μF of ceramic output capacitance and utilizes a unique compensation scheme to provide fast dynamic response to sudden line voltage and load current changes.

簡(jiǎn)介

TC1301A屬于集成電路（IC）的線性+開(kāi)關(guān)穩(wěn)壓器。由制造生產(chǎn)的TC1301A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(wú)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(gè)最小量，并且在工作時(shí)會(huì)將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對(duì)于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開(kāi)關(guān)模式的穩(wěn)壓器，但它們通常更適合對(duì)噪聲高度敏感的應(yīng)用。
