TLS203B0EJV中文资料汽车级线性稳压器数据手册Infineon规格书

描述 Description

Designed for use in battery-powered systems, the low quiescent current of 30 μA makes it an ideal choice.A key feature of the TLS203B0 is its low output noise. By adding an external 0.01 μF bypass capacitor, the output noise drops to very low numbers. The TLS203B0 voltage regulator is stable with output capacitors as small as 3.3 μF. Small ceramic capacitors can be used without the series resistance required by many other regulators. Internal protection circuitry includes reverse battery protection, current limiting and reverse current protection. The TLS203B0 comes as fixed output voltages 3.3 V, 5.0 V as well as an adjustable device with a 1.22 V reference voltage. It is available in a PG-DSO8 exposed pad package.

简介

TLS203B0EJV属于集成电路（IC）的线性+开关稳压器。由制造生产的TLS203B0EJV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。
