TPS75633KC屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由美國德州儀器公司制造生產(chǎn)的TPS75633KC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噪聲高度敏感的應(yīng)用。

DESCRIPTION

The TPS756xx family of 5-A low dropout (LDO)

regulators contains four fixed voltage option reguFixed-

lators and an adjustable voltage option regulator.

These devices are capable of supplying 5 A of output current with a dropout of 250 mV (TPS75633).

Therefore, the device is capable of performing a

3.3-V to 2.5-V conversion.

Quiescent current is 125 μA at full load and drops

down to less than 1 μA when the device is disabled.

The TPS756xx is designed to have fast transient

response for large load current changes.
