LD56020J110R集成電路（IC）的線性+開關穩(wěn)壓器規(guī)格書PDF中文資料

LD56020J110R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的LD56020J110R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 LD56020 is a high accuracy voltage regulator which provides 0.2 A of current.

It is available in CSP 0.65 x 0.65 mm2 package, SOT23-5L, allowing the maximum

space saving.

The device is stabilized with a small ceramic capacitor on input and output. The

ultra-low drop, low quiescent current and short-circuit current foldback make the

LD56020 suitable for low power battery-operated applications.

An enable logic control function puts the LD56020 in shutdown mode allowing a total

current consumption lower than 0.1 μA. Thermal protection is also included.
