描述 Description

Key Features:
? 1 % output voltage tolerance
? 0.01%/V line regulation
? 0.5% load regulation
? 0.02%/W thermal regulation The SG137A family of negative adjustable regulators will deliver up to 500mA output current over an output voltage range of -1.2V to -37V.? Microsemi has made significant improvements in these regulators compared to previous devices, such as better line and load regulation, and a maximum output voltage error of 1%.? The SG137 family uses the same chip design and guarantees maximum output voltage error of 2%.? Every effort has been made to make these devices easy to use and difficult to damage.? Internal current and power limiting coupled with true thermal limiting prevents device damage due to overloads or shorts even if the regulator is not fastened to a heat sink.? The SG137A/137 family of products are ideal complements to the SG117A/117 adjustable positive regulators.

簡介

SG137T屬于集成電路（IC）的線性+開關穩(wěn)壓器。由制造生產(chǎn)的SG137T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。
