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.

LD56020J180R屬于集成電路（IC） > 線性 + 開(kāi)關(guān)穩(wěn)壓器。意法半導(dǎo)體（ST）集團(tuán)制造生產(chǎn)的LD56020J180R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。
