TLE4253E規(guī)格書詳情
TLE4253E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TLE4253E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。
Functional Description
The TLE4253 is a monolithic integrated low-dropout voltage tracking regulator in small PG-DSO-8 packages. The exposed pad (EP) package variant PG-DSO-8 exposed pad offers extremely low thermal resistance. The IC is designed to supply off-board systems, e. g. sensors in engine management systems under the severe conditions of automotive applications. Therefore, the IC is equipped with additional protection functions against reverse polarity and short circuit to GND and battery.
With supply voltages up to 40 V, the output voltage follows a reference voltage applied at the adjust input with high accuracy. The reference voltage applied directly to the adjust input or by an e. g. external resistor divider can be 2.0 V at minimum.
The output is able to drive loads up to 250 mA at minimum while the device follows the e. g. 5 V output of a main voltage regulator acting as reference with high accuracy.
The TLE4253 tracker can be set into shutdown mode in order to reduce the quiescent current to an extremly low value. This makes the IC suitable to low power battery applications.
