LP2950ACZ-5.0RAG集成电路（IC）的线性+开关稳压器规格书PDF中文资料

LP2950ACZ-5.0RAG属于集成电路（IC）的线性+开关稳压器。由安森美半导体公司制造生产的LP2950ACZ-5.0RAG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。

The LP2950 and LP2951 are micropower voltage regulators that are specifically designed to maintain proper regulation with an extremely low input−to−output voltage differential. These devices feature a very low quiescent bias current of 75 A and are capable of supplying output currents in excess of 100 mA. Internal current and thermal limiting protection is provided.
