描述 Description

The IFX54211 is a monolithic integrated fixed linear voltage regulator for load currents up to 150 mA. The IC regulates an input voltage VIN up to 18 V to a fixed output voltage of 3.3 V with a precision of ±3 %. The IFX54211 is especially designed for applications requiring very low standby currents, e.g. with a permanent connection to a power supply, e.g. like a preregulating DCDC converter. Besides the very low quiescent current the current consumption of the device remains low also for higher load currents thanks to its PMOS powerstage. The IFX54211 combines in an ideal way a 150 mA current capability with extremely small package outlines, low dropout capability and high Power Supply Ripple Rejection PSRR over a wide frequency range. The component can be enabled/disabled via the Enable input. The device is available in a very small surface mounted PG-SCT595 package and is designed for the harsh environment of industrial applications. Therefore it is protected against overload, short circuit and overtemperature conditions by the implemented output current limitation and the overtemperature shutdown circuit. The IFX54211 can be also used in all other applications requiring a stabilized 3.3 V voltage.Sample available.Click here for Industrial Control Products Sample Kit

简介

IFX54211MBV33属于集成电路（IC）的线性+开关稳压器。由制造生产的IFX54211MBV33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。
