3 Description

The TLV704 low-dropout (LDO) linear voltage

regulator is a low quiescent current device that

offers the benefits of a wide input voltage range

and low-power operation in miniaturized packaging.

Thus, the TLV704 is designed for battery-powered

applications and as a power-management attachment

to low-power microcontrollers.

The TLV704 LDO supports a low dropout of typically

850 mV at 100 mA of load current. The low quiescent

current (3.4 μA typically) is stable over the entire

range of output load current (0 mA to 150 mA). The

TLV704 also features an internal soft-start to lower the

inrush current. The built-in overcurrent limit protection

helps protect the regulator in the event of a load short

or fault.

The TLV704 is available in a 2.90-mm × 1.60-mm

SOT23-5 package, which is useful for cost-effective

board manufacturing.

TLV70450DBVR屬于集成電路（IC） > 線性 + 開(kāi)關(guān)穩(wěn)壓器。美國(guó)德州儀器公司制造生產(chǎn)的TLV70450DBVR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。
