TLS850D0TEV50数据手册集成电路（IC）的线性+开关稳压器规格书PDF

描述 Description

The TLS850D0TEV50 is a high performance very low dropout linear voltage regulator for 5 V supply in a PG-TO252-5 package. With an input voltage range of 3 V to 40 V and very low quiescent of only 40 μA, these regulators are perfectly suitable for automotive or any other supply systems connected to the battery permanently. The TLS850D0TAV50 provides an output voltage accuracy of 2 % and a maximum output current up to 500 mA. The new loop concept combines fast regulation and very good stability while requiring only one small ceramic capacitor of 1 μF at the output. At currents below 100 mA the device will have a very low typical dropout voltage of only 70 mV. The operating range starts already at input voltages of only 3 V (extended operating range). This makes the TLS850D0TAV50 also suitable to supply automotive systems that need to operate during cranking condition.

简介

TLS850D0TEV50属于集成电路（IC）的线性+开关稳压器。由制造生产的TLS850D0TEV50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。
