TLS208D1集成電路（IC）的線性+開關(guān)穩(wěn)壓器規(guī)格書PDF中文資料

TLS208D1屬于集成電路（IC）的線性+開關(guān)穩(wěn)壓器。由英飛凌科技股份公司制造生產(chǎn)的TLS208D1穩(wěn)壓器 - 線性線性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無論負載電流、輸入電壓或環(huán)境因素如何變化，這些輸出電壓通常都要保持不變。它們的工作原理要求輸入電壓維持在高于所需的輸出電壓，而且要超出某個最小量，并且在工作時會將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開關(guān)模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應(yīng)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.
