LM2931D集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

LM2931D屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由意法半導(dǎo)體集團(tuán)制造生產(chǎn)的LM2931D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 LM2931xx are very low drop regulators. The very low drop voltage and the low quiescent current make them particular suitable for low noise, low power applications and in battery powered systems. In the 8 pin configuration (SO-8), fully compatible to the older L78Lxx family, a shut down logic control function is available.

Features

■ Very low dropout voltage (0.15 V typ. at 10 mA load)

■ Low quiescent current (typ. 2.5 mA, at 100 mA load)

■ Output current up to 100 mA

■ Adjustable (from VOUT= 2.5 V only SO-8) and fixed (3.3 V & 5 V) output voltage version

■ Internal current and thermal limit

■ Load dump protection up to 60 V

■ Reverse transient protection up to -50 V

■ Temperature range: -40 to 125 °C

■ Package available: TO-92, DPAK, SO-8 (with inhibit control)
