TLS850B0TEV50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 TLS850B0TEV50 is a high performance, very low dropout linear voltage regulator for 5.0 V supply in a PGTO252-5 package. The input voltage range of 3 V to 40 V and a very low quiescent current of 20 μA make it the perfect match for automotive or other supply systems connected to the battery permanently. The new loop concept combines fast regulation and very high stability. Below an output current of 100 mA the typical dropout voltage is below 100mV. The operating range starts at an input voltage of only 3 V (extended operating range). This makes the TLS850B0TEV50 suitable for automotive systems that need to operate during cranking condition. The device can be switched on and off by the Enable feature. Internal protection features such as output current limitation and overtemperature shutdown protect the device from immediate damage due to failures such as output shorted to GND, overcurrent and overtemperature.

简介

TLS850B0TEV50属于集成电路（IC）的线性+开关稳压器。由制造生产的TLS850B0TEV50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。
