MC78T12CT集成電路（IC）的線性+開關穩(wěn)壓器規(guī)格書PDF中文資料

MC78T12CT屬于集成電路（IC）的線性+開關穩(wěn)壓器。由安森美半導體公司制造生產的MC78T12CT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換為熱量。對于大多數應用而言，雖然這種穩(wěn)壓器的效率低于開關模式的穩(wěn)壓器，但它們通常更適合對噪聲高度敏感的應用。

3.0 A Positive Voltage Regulators

This family of fixed voltage regulators are monolithic integrated circuits capable of driving loads in excess of 3.0 A. These three?terminal regulators employ internal current limiting, thermal shutdown, and safe?area compensation. Devices are available with improved specifications, including a 2 output voltage tolerance, on AC?suffix 5.0 V, 12 V and 15 V device types.

Although designed primarily as a fixed voltage regulator, these devices can be used with external components to obtain adjustable voltages and currents. This series of devices can be used with a series?pass transistor to supply up to 15 A at the nominal output voltage.
