SG723T-883B中文资料High-Reliability Power Management数据手册Microchip规格书

描述 Description

Key Features:
• Positive or negative supply operation
• Series, shunt, switching or floating operation
• Low line and load regulation
• Output adjustable from 2V to 37V
• Output current to 150 mA
• Low standby current drain
• 0.002%/°C average temperature variation This monolithic voltage regulator is designed for use with either positive or negative supplies as a series, shunt, switching, or floating regulator with currents up to 150mA. Higher current requirements may be accommodated through the use of external NPN or PNP power transistors. This device consists of a temperature compensated reference amplifier, error amplifier, power series pass transistor, current limit, and remote shutdown circuitry. The SG723 will operate over the full military ambient temperature range of -55°C to 125°C.

简介

SG723T-883B属于集成电路（IC）的线性+开关稳压器。由制造生产的SG723T-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。
