描述 Description

Key Features:
? Input voltage range of 4.5V to 50V
? 2.5V low noise reference
? Independent shutdown terminal
? Improved line and load regulation
? 80mV current limit sense voltage
? Fully protected including thermal shutdown · Useful output current to 150mA This monolithic integrated circuit is a versatile, general-purpose voltage regulator designed as a substantially improved replacement for the popular SG723 device. The SG1532 series regulators retain all the versatility of the SG723 but have the added benefits of operation with input voltages as low as 4.5 volts and as high as 50 volts; a low noise, low voltage reference; temperature compensated, low threshold current limiting; and protective circuits which include thermal shutdown and independent current limiting of both the reference and output voltages. A separate remote shutdown terminal is included . In the dual-in-line package an open collector output is available for low input-output differential applications. These devices are available in both hermetic 14-pin cerdip and 10-pin TO-96 packages. In the T-package, these units are interchangeable with the LAS-1000 and LAS-1100 regulators. The SG1532 is rated for operation over the ambient temperature range of -55°C to 125°C while the SG2532 and SG3532 are intended for industrial applications of 0°C to 70°C.

簡介

SG1532J屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由制造生產(chǎn)的SG1532J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(zhuǎn)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(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用。
