路適用于小電流負載。 ( 2)系統(tǒng)分析:根據(jù)系統(tǒng)功能,選擇各模塊所用電路形式。 首先,根據(jù)任務(wù)的繁雜程度和技術(shù)指標(biāo)要求選擇 電路 。 關(guān)鍵詞: 三端集成 可調(diào)式 穩(wěn)壓器 直流穩(wěn)壓電源 集成芯片 Abstract Using integrated threeterminal Mc7815bt positive voltage output and upc7924 negative output voltage adjustable voltage regulator, the output voltage from 0 and 0 to 24 v to 15 v adjustable voltage for use between bination form between 039 v adjustable voltage for use in power amplifier. The regulated power supply with stable performance. The structure is simple, high precision of voltage, current indicators. The advantages of convenient adjustment. The bination of the adjustable threeterminal voltage regulator of the output voltage is adjustable, stabilizing the output ripple is small, the output voltage of 0 ~ 39 v adjustable, if you want to achieve high stability, with overcurrent protection is generally to adjust the output voltage is about 0 to 30 v. So its good performance and high reliability. And because of this stabilizer has the advantages of small volume, convenient use and low price, so widely used. This paper introduces the integrated threeterminal Mc7815bt and upc7924 for voltage regulator adjustable dc regulated power supply design and production.
