2 Description

The TPS715 low-dropout (LDO) linear voltage

regulators are low quiescent current devices that

offer the benefits of a wide input voltage range and

low-power operation in miniaturized packaging. The

low dropout voltage and low quiescent current of

the TPS715 allows operation at extremely low power

levels. Thus, the TPS715 is designed for batterypowered

applications and as a power-management

attachment to low-power microcontrollers.

The TPS715 is available in both fixed and adjustable

versions. For more flexibility or higher output voltages,

the adjustable version uses feedback resistors to set

the output voltage from 1.205 V to 15 V. The TPS715

LDOs support a low dropout of typically 415 mV at

50 mA of load current. The low quiescent current

(3.2 μA typically) is stable over the entire range of

output load current (0 mA to 50 mA). The TPS715

also features an internal soft-start to lower the inrush

current. The built-in overcurrent limit helps protect the

regulator in the event of a load short or fault.

TPS71550DCKR屬于集成電路（IC） > 線性 + 開關(guān)穩(wěn)壓器。美國(guó)德州儀器公司制造生產(chǎn)的TPS71550DCKR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。
