7805 790578XX系列集成稳压器的典型应用电路如下图所示,这是一个输出正5V直流电压的稳压电源电路。

IC采用集成稳压器7805,C1、C2分别为输入端和输出端滤波电容,RL为负载电阻。

当输出电较大时,7805应配上散热板。

下图为提高输出电压的应用电路。

稳压二极管VD1串接在78XX稳压器2脚与地之间,可使输出电压Uo得到一定的提高,输出电压Uo为78XX稳压器输出电压与稳压二极管VC1稳压值之和。

VD2是输出保护二极管,一旦输出电压低于VD1稳压值时,VD2导通,将输出电流旁路,保护7800稳压器输出级不被损坏。

下图为输出电压可在一定范围内调节的应用电路。

由于R1、RP电阻网络的作用,使得输出电压被提高,提高的幅度取决于R P与R1的比值。

调节电位器RP,即可一定范围内调节输出电压。

当RP=0时,输出电压Uo等于78XX稳压器输出电压;当RP逐步增大时,Uo也随之逐步提高。

下图为扩大输出电流的应用电路。

VT2为外接扩流率管,VT1为推动管,二者为达林顿连接。

R1为偏置电阻。

该电路最大输出电流取决于VT2的参数。

下图为提高输入电压的应用电路。

78XX稳压器的最大输入电压为35V(7824为40V),当输入电压高于此值时,可采用下图所示的电路。

VT、R1和VD组成一个预稳压电路,使得加在7800稳压器输入端的电压恒定在VD的稳压值上(忽略VT的b-e结压降)。

Ui端的最大输入电压仅取决于VT的耐压。

集成稳压器还可以用作恒流源。

下图为78XX稳压器构成的恒流源电路,其恒定电流Io等于78XX稳压器输出电压与R1的比值。

79XX系列集成压器是常用的固定负输出电压的三端集成稳压器,除输入电压和输出电压均为负值外,其他参数和特点与78XX系列集成稳压器相同。

79XX系列集成稳压的三个引脚为:1脚为接地端,2脚为输入端,3脚为输出端。

79XX系列集成稳压器的应用电路也很简单。

下图所示为输出-5V直流电压的稳压电源电路,IC采用集成稳压器7905,输出电流较大时应配上散热板。

LM337的典型应用电路如下图所示:
芯片的输出电压由R1和R2的比值决定,当固定R1 为120Ω时,其输出电压可由以下公式得出: Vout=-1.25V*(1+R2/R1).当输入滤波电路离芯片的 距离超过10cm时需加输入电容Cin.
在LM317和LM337的使用过程中需要注意以下问题: ⑴当输出功率过大时应加散热片,以免烧毁芯片。 ⑵芯片的in和out间的压差不能超过35V, ⑶芯片使用时,如果R2并联一个电容,可以大幅提高抵 抗谐波的能力.并联一个电容的同时,应该多加一个二 极管,使得电容放电时,保护芯片不受损坏。
常用电源芯片的使用
一、常用电源芯片分类
根据调整管的工作状态,我们常把稳压电源分成两类:
1、线性稳压电源
电压反馈电路工作在线性(放大)状态,线性稳压直流电源的特 点是: ⑴输出电压比输入电压低; ⑵反应速度快,输出纹波较小; ⑶工作产生的噪声低; ⑷效率较低(现在经常看的LDO就是为了解决效率问题 而出 现的); ⑸发热量大(尤其是大功率电源),间接地给系统增加热噪 声
78/79系列集成稳压器的典型应用电路如下图所示
实际应用注意事项: ⑴实际应用时应在三端集成稳压芯片上安装足够大 的散热器(小功率的条件下不用),当稳压管温度 过高时,稳压性能将变差,甚至损坏。 ⑵当需要一个能输出1.5A以上电流的稳压电源时, 通常采用几块三端稳压电路并联起来,使其最大输 出电流为N个1.5A,但应使用同一厂家、同一批次 的产品。 ⑶78/79系列的稳压集成块的极限输入电压是36V, 最低输入电压为输出电压的3-4V以上。
AMS1117可调电压的电路如下所示:
AMS1117在输出端和可调端之间提供1.25V的参考电压, 可根据需要通过电阻倍压的方式调整到所需要的电压, 图中R1,R2为倍增电阻。输出电压等于 Vout=Vref*(1+R2/R1)+IAdj*R2,由于IAdj较小(50uA 左右),远小于流过R1的电流(4mA左右),因此可 忽略。

芯片替换

芯片替换

一:LM78XX的缺点LM78XX是线性稳压电路,所有有其特有的内部功率损耗大,全部压降均转换为热量损失了,效率低.所以散热问题要特别注意.二:78xx/79xx系列在降压电路中应注意以下事项:1、输入输出压差不能太大,太大则转换效率急速降低,而且容易击穿损坏;2、输出电流不能太大,1.5A是其极限值。

大电流的输出,散热片的尺寸要足够大,否则会导致高温保护或热击穿;3、输入输出压差也不能太小,大小效率很差。

三:LM78XX的替换(1)LM2596替换LM7805LM2596的效率高,IC的发热量小,输出噪音大些。

LM7805的稳压效果好些,效率低,IC的发热量较大,输出噪音小2596是DC-DC,开关频率150KHZ,转换效率达95%以上,效率高,功率大,耗散小,但是价格较贵,外围配套电路复杂。

7805是LDO,转换效率低,热耗散大,价格便宜,外围电路简单(2)LM78XX-1A替换LM78XX针对线性稳压器78xx的效率会随着输入/输出电压差加大而急剧下降的特点,TEN-POWER 推出的LM78xx-1A系列开关三端稳压器,拥有高效率、小封裝尺寸,无须外加散热片,可以用来直接替换传统线性稳压器78xx。

TEN-POWER的标准LM78xx-1A系列开关三端稳压器,拥有高效率、小封裝尺寸,和传统线性稳压器78xx管脚兼容的优点。

线性稳压器78xx的效率会随着输入/输出电压差加大而急剧下降,而TEN-POWER 的LM78xx-1A系列在输入/输出电压变化仅几伏时具有96%的最高效率。

即使在输入电压高于输出电压15V时候仍可达到87%的效率,高效率使其不需要任何散热片,这是TEN-POWER相对于竞争者的主要优势:许多厂商都声称在理想条件下拥有高转换效率,只有LM78xx-1A系列能够在整个输入电压范围内提供高效率,即使在负载由20%变化到100%依然能够保持几乎恒定的效率。

极小的封装体积(11.5*10.0*6.0mm)最大程度的节省PCB成本和布线,同时拥有极高的功率密度—15W/cm3:所有型号都能1A连续输出电流和3A峰值电流拥有多重保护功能:过载、短路和过热保护工作温度覆盖整个-40℃至+85℃工业范围全面的电压型号:。

三端集成稳压器78XX-79XX系列的特点

三端集成稳压器78XX-79XX系列的特点

三端集成稳压器78XX/79XX系列的特点
三端固定输出集成稳压器是一种串联调整式稳压器。

它将全部电路集
成在单块硅片上,整个集成稳压电路只有输入、输出和公共3 个引出端,使用非常方便。

典型产品有78XX 正电压输出系列和79XX 负电压输出系列。


封装形式和引脚功能如图1 所示,其中,图(a)为78XX 系列的正电压输出,图(b)为79XX 系列的负电压输出。

图1 三端固定输出集成稳压器的封装形式和引脚功能
78XX/79XX 系列中的型号ⅩⅩ表示集成稳压器的输出电压的数值,以
V 为单位。

每类稳压器电路输出电压有5V,
6V,7V,8V,9V,10V,12V,15V,18V,24V 等,能满足大多数电子设各所需要的电源电压。

中间的字母通常表示电流等级,输出电流一般分为3 个等级:100mA(78LXX/79LXX),500mA(78MXX/79MXX),
1.5A(78XX/79XX )。

后缀英文字母表示输出电压容差与封装形式等。

内部电路由恒流源、基准电压源、取样电阻、比较放大、调整管、保护
电路、温度补偿电路等组成。

输出电压值取决于内部取样电阻的数值。

最大输出电压为40V。

三端固定输出电压集成稳压器,因内部有过热、过流保护电路,因此它
的性能优良,可靠性高。

又因这种稳压器具有体积小、使用方便、价格低廉等优点,所以得到广泛应用。

三端稳压器78xx79xx系列芯片介绍

三端稳压器78xx79xx系列芯片介绍

三端稳压器78xx79xx系列芯片介绍关键词:电路介绍三端稳压电子产品中常见到的三端稳压集成电路有正电压输出的78 ×× 系列和负电压输出的79××系列。

故名思义,三端IC是指这种稳压用的集成电路只有三条引脚输出,分别是输入端、接地端和输出端。

它的样子象是普通的三极管,TO- 220 的标准封装,也有9013样子的TO-92 封装。

用 78/79系列三端稳压IC 来组成稳压电源所需的外围元件极少,电路内部还有过流、过热及调整管的保护电路,使用起来可靠、方便,而且价格便宜。

该系列集成稳压IC型号中的78或79后面的数字代表该三端集成稳压电路的输出电压,如7806表示输出电压为正6V,7909表示输出电压为负9V。

78/79系列三端稳压IC 有很多电子厂家生产,80年代就有了,通常前缀为生产厂家的代号,如TA7805是东芝的产品,AN7909是松下的产品。

(点击这里,查看有关看前缀识别集成电路的知识)有时在数字78或79后面还有一个M或L,如78M12或79L24,用来区别输出电流和封装形式等,其中78L调系列的最大输出电流为100mA ,78M系列最大输出电流为1A,78系列最大输出电流为1.5A。

它的封装也有多种,详见图。

塑料封装的稳压电路具有安装容易、价格低廉等优点,因此用得比较多。

79系列除了输出电压为负。

引出脚排列不同以外,命名方法、外形等均与78系列的相同。

因为三端固定集成稳压电路的使用方便,电子制作中经常采用,可以用来改装至⒃??奈妊沟缭矗?簿?S米鞯缱由璞傅墓ぷ鞯缭础5缏吠既缤妓?尽?注意三端集成稳压电路的输入、输出和接地端绝不能接错,不然容易烧坏。

一般三端集成稳压电路的最小输入、输出电压差约为2V,否则不能输出稳定的电压,一般应使电压差保持在4-5V,即经变压器变压,二极管整流,电容器滤波后的电压应比稳压值高一些。

在实际应用中,应在三端集成稳压电路上安装足够大的散热器(当然小功率的条件下不用)。

温湿度测量

温湿度测量

一.湿度测量的基本概念 在工农业生产、气象、环保、国防、科
研、航天等部门,经常需要对环境湿度进行 测量及控制。对环境温、湿度的控制以及对 工业材料水份值的监测与分析都已成为比较 普遍的技术条件之一,但在常规的环境参数中, 湿度是最难准确测量的一个参数。这是因为 测量湿度要比测量温度复杂得多,温度是个 独立的被测量,而湿度却受其他因素(大气 压强、温度)的影响。此外,湿度的校准也 是一个难题。国外生产的湿度标定设备价格 十分昂贵。 室内测量温湿度用户手册
4.单片机部分选用M16,DHT11传出的数字信号经单
片机分析处理后交由显示部分来显示。

直流稳压电源结构图和稳压过程
1.电源变压器
电源变压器的作用是将来自电网的220V交流电压u1变换 为整流电路所需要的交流电压u2。电源变压器的效率为:
P2
P1
其中: 是变压器副边的功率, 是变压器原边的功率。
温湿度采集部分
方案一:采用热敏电阻、湿敏电阻。但湿、 热敏电阻精度、重复性、可靠性较差,对于 检测要求精度高的温湿度是不适用的。
方案二:采用集成温湿度传感器。集成温湿 度传感器测量精度高,能把温度转化成数字, 测得的温湿度值的存储在自带RAM中,单片 机直接从中读出数据转换成十进制就是温度, 使用方便。
而电子式湿度传感器是近几十年,特别是近20年才 迅速发展起来的。湿度传感器生产厂在产品出厂前都要 采用标准湿度发生器来逐支标定,电子式湿度传感器的 准确度可以达到2%一3%RH。
湿度传感器是采用半导体技术,因此对使用的环境 温度有要求,超过其规定的使用温度将对传感器造成损 坏。
所以电子式湿度传感器测湿方法更适合于在洁净及 常温的场合使用。成品图

DESCRIPTION The L7900 series of three-terminal negative regulators is available in TO-220, TO-220FP, TO-3 and D2PAK packages and 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; furthermore, having the same voltage option as the L7800 positive standard series, they are particularly suited for split power supplies. If adequate heat sinking is provided, they can deliver over 1.5A output current. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents. SCHEMATIC DIAGRAM
