TLS208D1集成电路（IC）的线性+开关稳压器规格书PDF中文资料

TLS208D1属于集成电路（IC）的线性+开关稳压器。由英飞凌科技股份公司制造生产的TLS208D1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。

Description

The TLS208D1 is a monolithic integrated linear voltage post regulator. The IC regulates an input voltage VI in the

range of 2.7 V ≤ VI ≤ 18 V to an adjustable output voltage of 0.8 V to 5.25 V or to a fixed output voltage with a

precision of ±2 . The TLS208D1 is especially designed for applications with a permanent connection to

preregulators like DCDC converters. The device is available in the small surface mounted PG-DSO-8 (Exposed

Pad) package. 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

overtemperature conditions by the implemented output current limitation and the overtemperature shutdown

circuit. The TLS208D1 can be also used in all other applications requiring a stabilized voltage of 0.8 V to 5.25 V.

The input capacitor CI is recommended for compensating line influences. The output capacitor CQ is necessary

for the stability of the regulating circuit. Stability is guaranteed at values specified in “Functional Range” on

Page 8 within the whole operating temperature range.
