SG137AT-883B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:
• 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.

简介

SG137AT-883B属于集成电路（IC）的线性+开关稳压器。由制造生产的SG137AT-883B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。
