LM4128, LM4128Q SNVS475E–NOVEMBER2006–REVISEDAPRIL2013 www.ti.com APPLICATION INFORMATION THEORY OF OPERATION The foundation of any voltage reference is the band-gap circuit. While the reference in the LM4128 is developed from the gate-source voltage of transistors in the IC, principles of the band-gap circuit are easily understood usingabipolarexample.Foradetailedanalysisofthebipolarband-gapcircuit,seetheAN-56ApplicationReport (SNVA514). SUPPLY AND ENABLE VOLTAGES To ensure proper operation, V and V must be within a specified range. An acceptable range of input voltages EN IN is V >V +400mV(I ≤10mA) (1) IN REF LOAD The enable pin uses an internal pull-up current source (I ≊ 2 µA) that may be left floating or triggered by PULL_UP an external source. If the part is not enabled by an external source, it may be connected to V . An acceptable IN range of enable voltages is given by the enable transfer characteristics. See the Electrical Characteristicssection andEnableTransferCharacteristicsfigureformoredetail.Note,thepartwillnotoperatecorrectlyforV >V . EN IN COMPONENT SELECTION A small ceramic (X5R or X7R) capacitor on the input must be used to ensure stable operation. The value of C IN must be sized according to the output capacitor value. The value of C must satisfy the relationship C ≥ C . IN IN OUT When no output capacitor is used, C must have a minimum value of 0.1 µF. Noise on the power-supply input IN may affect the output noise. Larger input capacitor values (typically 4.7 µF to 22 µF) may help reduce noise on the output and significantly reduce overshoot during startup. Use of an additional optional bypass capacitor between the input and ground may help further reduce noise on the output. With an input capacitor, the LM4128 willdriveanycombinationofresistanceandcapacitanceuptoV /20mAand10µFrespectively. REF The LM4128 is designed to operate with or without an output capacitor and is stable with capacitive loads up to 10 µF. Connecting a capacitor between the output and ground will significantly improve the load transient response when switching from a light load to a heavy load. The output capacitor should not be made arbitrarily largebecauseitwilleffecttheturn-ontimeaswellaslineandloadtransients. While a variety of capacitor chemistry types may be used, it is typically advisable to use low esr ceramic capacitors. Such capacitors provide a low impedance to high frequency signals, effectively bypassing them to ground.Bypasscapacitorsshouldbemountedclosetothepart.Mountingbypasscapacitorsclosetothepartwill helpreducetheparasitictracecomponentstherebyimprovingperformance. SHORT CIRCUITED OUTPUT The LM4128 features indefinite short circuit protection. This protection limits the output current to 75 mA when theoutputisshortedtoground. TURN ON TIME Turn on time is defined as the time taken for the output voltage to rise to 90% of the preset value. The turn on timedependsontheload.Theturnontimeistypically33.2µswhendrivinga1µFloadand78.8 µswhendriving a 10 µF load. Some users may experience an extended turn on time (up to 10 ms) under brown out conditions andlowtemperatures(-40°C). THERMAL HYSTERESIS Thermal hysteresis is defined as the change in output voltage at 25ºC after some deviation from 25ºC. This is to say that thermal hysteresis is the difference in output voltage between two points in a given temperature profile.

LM4128, LM4128Q www.ti.com SNVS475E–NOVEMBER2006–REVISEDAPRIL2013 PRINTED CIRCUIT BOARD and LAYOUT CONSIDERATIONS References in SOT packages are generally less prone to PC board mounting than devices in Small Outline (SOIC) packages. To minimize the mechanical stress due to PC board mounting that can cause the output voltage to shift from its initial value, mount the reference on a low flex area of the PC board, such as near the edgeoracorner. The part may be isolated mechanically by cutting a U shape slot on the PCB for mounting the device. This approachalsoprovidessomethermalisolationfromtherestofthecircuit. Bypass capacitors must be mounted close to the part. Mounting bypass capacitors close to the part will reduce theparasitictracecomponentstherebyimprovingperformance.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. Addendum-Page 6

PACKAGE OPTION ADDENDUM www.ti.com 6-Feb-2020 (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
