描述 Description

The TLS208D1 is a monolithic integrated linear voltage post regulator. The IC regulates an input voltage VI in the range of 2.7V ≤ V I ≤ 18V to an adjustable output voltage of 0.8V to 5.25V or to a fixed output voltage with a precision of ±2 %. The TLS208D1 is especially designed for applications with a permanent connection to pre-regulators like DCDC converters. The device is available in the small surface mounted PG-DSO-8 (Exposed Pad) and TSON-10 packages. In addition to the enable functionality, the feature set includes a reset with an adjustable reset threshold. This threshold can be modified by an external resistor divider. The device is designed for the harsh environment of automotive applications. Therefore it is protected against overload, short circuit and over-temperature conditions by the implemented output current limitation and the over-temperature shutdown circuit. The input capacitor C I is recommended for compensating line influences. The output capacitor C Q is necessary for the stability of the regulating circuit.

简介

TLS208D1LDV33属于集成电路（IC）的线性+开关稳压器。由制造生产的TLS208D1LDV33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。
