TPS76650DRG4規(guī)格書(shū)詳情

TPS76650DRG4屬于集成電路(IC)的線性+開(kāi)關(guān)穩(wěn)壓器。由德州儀器制造生產(chǎn)的TPS76650DRG4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。

3 Description

The TPS766 is a low-dropout (LDO) linear voltage

regulator that supports an input voltage range from

2.5 V to 16 V (new chip) and up to 250 mA of load

current. For the new chip, the supported output range

is from 1.2 V to 12 V (fixed version) or from 0.8 V to

14.6 V (adjustable version).

The input voltage range is up to 16 V (new chip),

which makes the device a good choice for operating

from transformer secondary windings and regulated

rails (such as 10 V or 12 V). Additionally, the wide

output voltage range allows the device to generate

the bias voltage for silicon carbide (SiC) gate drivers

and microphones, as well as power microcontrollers

(MCUs) and processors.

Wide bandwidth PSRR performance is greater than

70 dB at 1 kHz and 46 dB at 1 MHz (new chip),

which helps attenuate the switching frequency of

an upstream DC/DC converter and minimizes post

regulator filtering. The new chip supports internal

soft-start circuit mechanism that reduces inrush

current during start-up, thus allowing for smaller input

capacitance.

The legacy chip supports constant quiescent current

across the complete load current range (typically 35

μA for the full range of output current, 0 mA to 250

mA).
