描述 Description

The SG109/SG309 is a completely self-contained 5V regulator. Designed to provide local regulation at currents up to 1A for digital logic cards, this device is available in the hermetic TO-3, TO-66, TO-39 and hermetic and plastic TO-220. A major feature of the SG109's design is its built-in protective features which make it essentially blowout proof. These consist of both current limiting to control the peak currents and thermal shutdown to protect against excessive power dissipation. With the only added component being a possible need for an input bypass capacitor, this regulator becomes extremely easy to apply. Utilizing an improved Bandgap reference design, problems have been eliminated that are normally associated with the zener diode references, such as drift in output voltage and large changes in the line and load regulation.FEATURES· Fully compatible with TTL and DTL· Output current in excess of 1A· Internal thermal overload protection· No additional external components· Bandgap reference voltage· Foldback current limiting HIGH RELIABILITY FEATURES-SG109·Available to MIL-STD-883·MIL - M38510 / 10701BXA - JAN109T·Radiation data available·LMI level \"S\" processing available

简介

SG109T-883B属于集成电路（IC）的线性+开关稳压器。由制造生产的SG109T-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。
