3.7V 400mA Low Dropout RegulatorFeaturesDropout voltage typically 0.8V @ I O = 400mA Output current in excess of 400mA Output voltage accuracy +3%/-2% Quiescent current, typically 600µA Internal short circuit current limit Internal over temperature protectionGeneral DescriptionThe G940/G941 positive 3.7V voltage regulator fea-tures the ability to source 400mA of output current with a dropout voltage of typically 0.8V over the en-tire operating temperature range. A low quiescent current is provided over the entire output current range. The typical quiescent current is 0.6mA. Fur-thermore, the quiescent current is smaller when the regulator is in the dropout mode (V IN < 3.7V).Familiar regulator features such as over temperature and over current protection circuits are provided to prevent it from being damaged by abnormal operating conditions.Ordering InformationPIN OPTIONORDER NUMBERPACKAGE TYPE1 2 3G940T21U SOT 89 V OUT GND V IN G941T24U SOT 89 GND V IN V OUT G940T73U SOT 23 GND V OUT V IN*For other package types, pin options and package, please contact us at sales @ Order Number IdentificationType Pin Option TypePart NumberPACKAGE TYPEPIN OPTIONPACKINGT2 : SOT 89 1 2 3U & D : Tape & Reel D DirectionT6 : SOT 223 1 : V OUT GNDV IN T : Tube T7 : SOT 23 2 : V OUTV INGND B : Bag T8 : µTO92 3 : GND V OUT V IN4 : GND V INV OUT 5 : V IN GNDV OUT6 : V IN V OUT GNDTypical Application Package Type[Note 4] : Type of C OUTSOT 893µTO 92SOT 23、223V OUTAbsolute Maximum Ratings (Note 1)Input Voltage……………………………..……..…..…10V Power Dissipation Internally Limited ..(Note 2) Maximum Junction Temperature………….….…...150°C Storage Temperature Range…..…..…..-65°C ≤ T J ≤+150°C Lead Temperature, Time for Wave SolderingSOT 89, SOT23 Package….….…..……..…....260°C, 4s Continuous Power Dissipation (T A = + 25°C)SOT 23(1)…….…………………….….……….……...0.3W SOT 89(1)……………………….………..………..…0.42WNote (1): See Recommended Minimum Footprint.Operating Conditions (Note 1)Input Voltage………………………….…………….4V~7V Temperature Range………………….…0°C ≤ T J ≤125°CElectrical CharacteristicsV IN =5V, I O = 400mA, C IN = 1 µF, C OUT =10 µF, All specifications apply for T A = T J = 25°C.

Operating Condi-tions are conditions under which the device functions but the specifications might not be guaranteed. For guaranteed specifications and test conditions see the Electrical Characteristics.Note 2: The maximum power dissipation is a function of the maximum junction temperature, T Jmax ; total thermal re-sistance, θJA , and ambient temperature T A . The maximum allowable power dissipation at any ambient tem-perature is T jmax -T A / θJA . If this dissipation is exceeded, the die temperature will rise above 130°C and ICwill go into thermal shutdown. For the G940/G941 in SOT 23 package, θJA is 350°C/W and in the SOT 89 package is 250°C/W (See Recommend Minimum Footprint). The safe operation in SOT 23 & SOT 89 package, it can see “Typical Performance Characteristics” (Safe Operating Area).Note3: Low duty pulse techniques are used during test to maintain junction temperature as close to ambient aspossible.Note4: The type of output capacitor should be tantalum or aluminum.DefinitionsDropout VoltageThe input/output Voltage differential at which the regulator output no longer maintains regulation against further reductions in input voltage. Measured when the output drops 100mV below its nominal value, dropout voltage is affected by junction temperature, load cur-rent and minimum input supply requirements.Line RegulationThe change in output voltage for a change in input voltage. The measurement is made under conditions of low dissipation or by using pulse techniques such that average chip temperature is not significantly af-fected.Load RegulationThe change in output voltage for a change in load current at constant chip temperature.

EH4说明书

一、EH4是全新概念的电导率张量测量仪通常意义下的电探仪，指的是交、直流电阻率剖面仪。

这两种方法都是有源测量方法，需要向地下直接供电，并且随着测量深度加大，电极布线和供电量都不断增加，野外劳动强度大，效率低。

另一方面，尽管这两种方法都属于有源电探，但采集到的视电阻率值都属于标量范畴，对辨别地下二度体异常的走向无能为力。

大地电磁同属于电探，但它是无源测量。

利用天然电磁场，虽然避免了大电流供电，但天然电磁场不稳定，而且某些频段先天不足，干扰强，讯号弱。

参看（图1）大地电磁场水平分量频谱展示图。

它反映了天然电磁场与人文电磁场的分布情况。

在1Hz左右，无论电场和磁场都是低谷；在1000Hz处磁场几近寂静，电场有一低谷。

在几十赫兹到104Hz范围内，人文活动的电磁场干扰特别严重。

这些特点决定了大地电磁法只适合于采集较低频率。

通常观测时间长，分辨率较低，适合解决深层宏观问题。

所以尽管电探方法起源最早，几十年来，由于以上的局限性，一直阻碍它的发展。

几十年来，1000米以内，几百米上下，正是人类经济、文明活动在地壳上层最活跃的深度。

其它物探方法，如地震勘探法，自40~50年代之后都开始大展身手，而浅、中深度范围的电探则相对寂寞冷落，处于陪衬地位。

也正是这种现状激发了国内外众多的科学家和仪器制造商不断研制开发新的电探仪器，寻找新的电探方法。

96年中下旬，由美国以研制大地电磁仪器而闻名的EMI公司和以制造高分辨率地震仪著名的Geometrics公司联合研制出EH4。

这是全新概念的电导率张量测量仪。

它利用大地电磁的测量原理，但配置了特殊的人工电磁波发射源。

这种发射源的天线是一对十字交叉的天线，组成X、Y两个方向的磁偶极子，轻便而且只用于普通汽车电瓶供电，发射率从500Hz到100KHz，专门用来弥补大地电磁场的寂静区和几百赫兹附近的人文电磁干扰谐波（见图1）。

仪器用反馈式高灵敏度低噪音磁棒和特制的电极，分别接收X、Y两个方向的磁场和电场。
