IFX2931GV33中文资料工业级线性稳压器数据手册Infineon规格书

描述 Description

The IFX2931 is a positive voltage regulator with a very low quiescent current of 1mA or less when supplying 10mA loads. The IFX2931GV50 also offers an extremely low dropout voltage required for proper regulation: 0.2V for output currents of 10mA. Therefore the IFX2931 is the ideal supply for standby power systems. It is suitable for e.g. memory standby circuits, CMOS and other low power processor power supplies. It certainly can also be used for any system demanding as much as 100mA of output current. The IFX2931 is protected from reverse polarity condition and can withstand input voltages of 28 V continously. The IFX2931 cannot be harmed by temporary mirror-image insertion. Additional protection features such as output current limitation and overtemperature shutdown are also implemented. The IFX2931 comes in an 8-lead SMD package (PG-DSO-8).

简介

IFX2931GV33属于集成电路（IC）的线性+开关稳压器。由制造生产的IFX2931GV33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。
