DESCRIPTION

The L78M00 series of three-terminal positive regulators is available in TO-220, TO-220FP,

DPAK and IPAK packages and with several fixed output voltages, making it useful in a wide range of applications. These regulators can provide local on-card regulation, eliminating the distribution

problems associated with single point regulation. Each type employs internal current limiting,

thermal shut-down and safe area protection, making it essentially indestructible. If adequate

heat sinking is provided, they can deliver over 0.5A output current. Although designed primarily

as fixed voltage regulators, these devices can be used with external components to obtain

adjustable voltage and currents.

■ OUTPUT CURRENT TO 0.5A

■ OUTPUT VOLTAGES OF 5; 6; 8; 9; 12; 15; 18; 20; 24V

■ THERMAL OVERLOAD PROTECTION

■ SHORT CIRCUIT PROTECTION

■ OUTPUT TRANSITION SOA PROTECTION

L78M05屬于集成電路（IC） > 線(xiàn)性 + 開(kāi)關(guān)穩(wěn)壓器。意法半導(dǎo)體（ST）集團(tuán)制造生產(chǎn)的L78M05穩(wěn)壓器 - 線(xiàn)性線(xiàn)性穩(wěn)壓器用于提供穩(wěn)定的輸出電壓，無(wú)論負(fù)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(gè)最小量，并且在工作時(shí)會(huì)將輸入端的任何多余電壓轉(zhuǎn)換為熱量。對(duì)于大多數(shù)應(yīng)用而言，雖然這種穩(wěn)壓器的效率低于開(kāi)關(guān)模式的穩(wěn)壓器，但它們通常更適合對(duì)噪聲高度敏感的應(yīng)用。
