TDA8133集成電路（IC）的線性+開關穩(wěn)壓器規(guī)格書PDF中文資料

TDA8133屬于集成電路（IC）的線性+開關穩(wěn)壓器。由意法半導體集團制造生產(chǎn)的TDA8133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，而且要超出某個最小量，并且在工作時會將輸入端的任何多余電壓轉換為熱量。對于大多數(shù)應用而言，雖然這種穩(wěn)壓器的效率低于開關模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應用。

Description

The TDA8133 and the TDA8133D are monolithic dual positive voltage regulators designed to provide fixed precision output voltages of 5.1 V and 8.0 V for currents up to 750 mA.

An internal reset circuit generates a reset pulse when the voltage of output 1 drops below the regulated voltage value.

Output 2 can be disabled via the TTL input.

Short-circuit and thermal protections are included in all versions.
