TPS71550QDCKRQ1集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

TPS71550QDCKRQ1屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由德州儀器制造生產(chǎn)的TPS71550QDCKRQ1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。

3 Description

The TPS715-Q1 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 TPS715-Q1 is designed for battery-powered

applications and as a power-management attachment

to low-power microcontrollers.

The TPS715-Q1 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 1.2 V to

15 V. The TPS715-Q1 LDO supports 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-Q1 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.

The TPS715-Q1 is available in a 2.00 mm × 1.25 mm,

5-pin SC-70 (DCK) package for fixed and adjustable

outputs.
