当 UVLO 引脚低于 0.4V 时，稳压器处于关断模式，所有功能被禁用。
如果UVLO 引脚电压高于 0.4V 并低于 1.25V，稳压器随 VCC 稳压器运行而处于待机模式，此时 SS 引脚接地，且 HO 和 LO 输出端不会切换。
如果 UVLO 引脚电压高于 1.25V，SS 引脚允许电压上升，同时脉宽调制栅极驱动信号传递至 HO 和 LO 引脚。
当 UVLO 超过 1.25V，且流经外部 UVLO 电阻时，20 µA 灌电流被激活以提供迟滞。

Normally, only a single 1-µF solid tantalum output capacitor is required unless the device is situated more than 6 inches from the input filter capacitors, in which case an input bypass is required. A larger output capacitor can be added to improve transient response. The adjustment pin can be bypassed to achieve very high ripple rejection ratios, which are difficult to achieve with standard 3-pin regulators.

IGBT Drive Negative Gate Supplies ?Networking ?Set-Top Boxes 3Description The LM337L is an adjustable 3-pin negative voltage regulator capable of supplying 100mA over a –1.2-V to –37-V output range.The LM337L is easy to use and requires only two external resistors to set the output voltage.Both line and load regulation are better than standard fixed regulators.The LM337L is packaged in a standard,easy-to-use TO-92transistor package.In addition to higher performance than fixedregulators,the LM337L offers full overload protection.Included on the chip are current limit,thermaloverload protection,and safe area protection.Alloverload protection circuitry remains fully functionaleven if the adjustment pin is disconnected.Normally,only a single 1-µF solid tantalum output capacitor is required unless the device is situated more than 6inches from the input filter capacitors,in which case an input bypass is required.A larger output capacitor can be added to improve transient response.The adjustment pin can be bypassed to achieve very high ripple rejection ratios,which are difficult to achieve with standard 3-pin regulators.Besides replacing fixed regulators,the LM337L is useful in a wide variety of other applications.Because the regulator is floating and monitors only the input-to-output differentialvoltage,supplies of severalhundred volts can be regulated as long as themaximum input-to-output differential is not exceeded.The LM337L makes a simple adjustable switchingregulator,a programmable output regulator,or byconnecting a fixed resistor between the adjustmentand output,the LM337L can be used as a precisioncurrent regulator.Supplies with electronic shutdowncan be achieved by clamping the adjustment pin toground,which programs the output to 1.2V,wheremost loads draw little current.The LM337L is available in a standard TO-92transistor package and a standard SO-8surfacemount package.The LM337L is rated for operationover a –25°C to 125°C range.For applications requiring output current in excess of0.5A and 1.5A,The LM137series may be suitable.For the positive complement,the LM117and LM317Lseries are options.Device Information (1)PART

Description7.1OverviewThe LM337L devices are adjustable 3-terminal negative-voltage regulators capable of supplying 100mA over anoutput voltage range of –1.2V to –37V.They are exceptionally easy to use,requiring only two external resistorsto set the output voltage and one output capacitor for frequency compensation.In addition,LM337L offers fulloverload protection.Included on the chip are current limit,thermal overload protection and safe area protection.All overload protection circuitry remains fully functional even if the adjustment terminal is disconnected.TheLMx37devices serve a wide variety of applications,including local on-card regulation,programmable output-voltage regulation,and precision current regulation.7.2Functional Block Diagram7.3Feature Description7.3.1Output Voltage AdjustmentThe Adjustment (ADJ)pin serves as a voltage adjustment reference for the output.The ADJ pin can be attachedto a resistor divider circuit to adjust the output voltage level.The reference voltage VADJ will typically be 1.25Vhigher than VO.7.4Device Functional Modes7.4.1Protection DiodesWhen external capacitors are used with any IC regulator,it is sometimes necessary to add protection diodes toprevent the capacitors from discharging through low current points into the regulator.Most 10-µF capacitors havelow enough internal series resistance to deliver 20-A spikes when shorted.Although the surge is short,there isenough energy to damage parts of the IC.When an output capacitor is connected to a negative output regulatorand the input is shorted,the output capacitor pulls current out of the output of the regulator.The current dependson the value of the capacitor,the output voltage of the regulator,and the rate at which VIN is shorted to ground.The bypass capacitor on the adjustment terminal can discharge through a low current junction.Discharge occurswhen either the input,or the output,is shorted.Figure 15shows the placement of the protection diodes.LM337L /doc/c345595427fff705cc1755270722192e453658bd.html SNVS780E–MAY1998–REVISED DECEMBER2016 Device Functional Modes(continued)When CL is larger than20µF,D1protects the LM337L in case the

following applications sections is not part of the TI componentspecification,and TI does not warrant its accuracy or completeness.TI’s customers areresponsible for determining suitability of components for their purposes.Customers shouldvalidate and test their design implementation to confirm system functionality.8.1Application InformationThe LM337L is a negative output linear regulator with high accuracy and a wide temperature range.An outputcapacitor can be added to further improve transient response,and the ADJ pin can be bypassed to achieve veryhigh ripple-rejection ratios.The device's functionality can be utilized in many different applications that requirenegative voltage supplies,such as bipolar amplifiers,operational amplifiers,and constant current regulators.8.2Typical

is very minimal,employing two resistors as part of a voltage divider circuit and anoutput capacitor for load regulation.An input capacitor is needed if the device is more than 4in.from the filtercapacitors.8.2.1.2Detailed Design ProcedureThe output voltage is set based on the selection of the two resistors (R1and R2)as shown in Equation 1.(1)-22 VCopyright ? 2016, Texas Instruments

used for a voltage divider circuit and the other three used for trimming the output voltage.The benefit is lower cost as compared to using a trim pot.An output capacitor is needed to improve load regulation.8.2.2.2Detailed Design ProcedureThis design will trim the output voltage to within1%of–22V.The parallel combination of R1,R3,R4and R5 serve as the bottom resistance and R2as the top resistance in the voltage divider that sets the output voltage. Trim Procedure:If V OUT is–23.08V or larger,do not use R3,otherwise leave it in.Then if V OUT is–22.47V or bigger,do not use R4,otherwise leave it in.Then if V OUT is–22.16V or bigger,do not use R5,otherwise leave it in.This will trim the output to well within1%of–22V DC,without any of the expense or trouble of a trim pot(see LB-46).This technique can be used at any output voltage level.LM337LSNVS780E–MAY1998–REVISED /doc/c345595427fff705cc1755270722192e453658bd.html 9Power Supply RecommendationsThe input supply to the LM337L must be kept at a voltage level such that its maximum input to output differential voltage rating is not exceeded.The minimum dropout voltage must also be met with extra headroom when possible to keep the LM337L in regulation.TI recommends an input capacitor,especially when the input pin is placed more than4in.away from the power-supply filter capacitor.10Layout10.1Layout GuidelinesSome layout guidelines must be followed to ensure proper regulation of the output voltage with minimum noise. Traces carrying the load current must be wide to reduce the amount of parasitic trace inductance and the feedback loop from VOUT to ADJ must be kept as short as possible.To improve PSRR,a bypass capacitor can be placed at the ADJ pin and must be placed as close as possible to the IC.In cases when VIN shorts to ground, an external diode must be placed from VIN to VOUT to divert the surge current into the output capacitor and protect the IC.Similarly,in cases when a large bypass capacitor is placed at the ADJ pin and VOUT shorts to ground,an external diode must be placed from VOUT to ADJ to provide a path for the bypass capacitor to discharge.These diodes must be placed close to the corresponding IC pins to increase their effectiveness.10.2Layout ExampleFigure9.LM337L Layout ExampleLM337L /doc/c345595427fff705cc1755270722192e453658bd.html SNVS780E–MAY1998–REVISED DECEMBER201611Device and Documentation Support11.1Documentation Support11.1.1Related DocumentationFor related documentation see the following:LM317L-N3-Terminal Adjustable Regulator(SNOSBW2)LM117,LM317-N Wide Temperature Three-Pin Adjustable Regulator(SNVS774)LM317L-N3-Terminal Adjustable Regulator(SNVS775)11.2Receiving Notification of Documentation UpdatesTo receive notification of documentation updates,navigate to the device product folder on /doc/c345595427fff705cc1755270722192e453658bd.html .In the upper right corner,click on Alert me to register and receive a weekly digest of any product information that has changed.For change details,review the revision history included in any revised document.11.3Community ResourcesThe following links connect to TI community resources.Linked contents are provided"AS IS"by the respective contributors.They do not constitute TI specifications and do not necessarily reflect TI's views;see TI's Terms of Use.TI E2E?Online Community TI's Engineer-to-Engineer(E2E)Community.Created to foster collaboration among engineers.At/doc/c345595427fff705cc1755270722192e453658bd.html ,you can ask questions,share knowledge,explore ideas and helpsolve problems with fellow engineers.Design Support TI's Design Support Quickly find helpful E2E forums along with design support tools and contact information for technical support.11.4TrademarksE2E is a trademark of Texas Instruments.All other trademarks are the property of their respective owners.11.5Electrostatic Discharge CautionThis integrated circuit can be damaged by ESD.Texas Instruments recommends that all integrated circuits be handled with appropriate precautions.Failure to observe proper handling and installation procedures can cause damage.ESD damage can range from subtle performance degradation to complete device failure.Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 11.6GlossarySLYZ022—TI Glossary.This glossary lists and explains terms,acronyms,and definitions.12Mechanical,Packaging,and Orderable InformationThe following pages include mechanical,packaging,and orderable information.This information is the most current data available for the designated devices.This data is subject to change without notice and revision of this document.For browser-based versions of this data sheet,refer to the left-hand navigation.PACKAGING INFORMATION(1) The marketing status values are defined as follows:ACTIVE: Product device recommended for new designs.LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.NRND: Not recommended for new designs.
