LM317LZREG集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

LM317LZREG屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由安森美半導(dǎo)體公司制造生產(chǎn)的LM317LZREG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，而且要超出某個最小量，并且在工作時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。

The LM317L is an adjustable 3?terminal positive voltage regulator

capable of supplying in excess of 100 mA over an output voltage range

of 1.2 V to 37 V. This voltage regulator is exceptionally easy to use

and requires only two external resistors to set the output voltage.

Further, it employs internal current limiting, thermal shutdown and

safe area compensation, making them essentially blow?out proof.

The LM317L serves a wide variety of applications including local,

on card regulation. This device can also be used to make a

programmable output regulator, or by connecting a fixed resistor

between the adjustment and output, the LM317L can be used as a

precision current regulator.
