SG1532J数据手册集成电路（IC）的线性+开关稳压器规格书PDF

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.

简介

SG1532J属于集成电路（IC）的线性+开关稳压器。由制造生产的SG1532J稳压器 - 线性线性稳压器用于提供稳定的输出电压，无论负载电流、输入电压或环境因素如何变化，这些输出电压通常都要保持不变。它们的工作原理要求输入电压维持在高于所需的输出电压，而且要超出某个最小量，并且在工作时会将输入端的任何多余电压转换为热量。对于大多数应用而言，虽然这种稳压器的效率低于开关模式的稳压器，但它们通常更适合对噪声高度敏感的应用。
