LM723QML Voltage Regulator
Literature Number: SNVS310
LM723QML
Voltage Regulator
General Description
Features
The LM723 is a voltage regulator designed primarily for
series regulator applications. By itself, it will supply output
currents up to 150 mA; but external transistors can be added
to provide any desired load current. The circuit features
extremely low standby current drain, and provision is made
for either linear or foldback current limiting.
n 150 mA output current without external pass transistor
n Output currents in excess of 10A possible by adding
external transistors
n Input voltage 40V max
n Output voltage adjustable from 2V to 37V
n Can be used as either a linear or a switching regulator
The LM723 is also useful in a wide range of other applications such as a shunt regulator, a current regulator or a
temperature controller.

Note 1: “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.
Note 2: The maximum power dissipation for these devices must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature,
TA. The maximum available power dissipation at any temperature is Pd = (TJMAX − TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is less.
See derating curves for maximum power rating above 25˚C.
Note 3: Human body model, 1.5 kΩ in series with 100 pF.
Note 4: L1 is 40 turns of No. 20 enameled copper wire wound on Ferroxcube P36/22-3B7 pot core or equivalent with 0.009 in. air gap.
Note 5: Figures in parentheses may be used if R1/R2 divider is placed on opposite input of error amp.
Note 6: Replace R1/R2 in figures with divider shown in Figure 13.
Note 7: V+ and VCC must be connected to a +3V or greater supply.
Note 8: For metal can applications where VZ is required, an external 6.2V zener diode should be connected in series with VOUT.
Note 9: Unless otherwise specified, TA = 25˚C, VIN = V+ = VC = 12V, V− = 0, VOUT = 5V, IL = 1 mA, RSC = 0, C1 = 100 pF, CREF = 0 and divider impedance as seen
by error amplifier ≤ 10 kΩ connected as shown in Figure 1 Line and load regulation specifications are given for the condition of constant chip temperature.
Temperature drifts must be taken into account separately for high dissipation conditions.
Note 10: Tested for DIPS only.

which, (a) are intended for surgical implant into the body, or
(b) support or sustain life, and whose failure to perform when
properly used in accordance with instructions for use
provided in the labeling, can be reasonably expected to result
in a significant injury to the user.
2. A critical component is any component of a life support
device or system whose failure to perform can be reasonably
expected to cause the failure of the life support device or
system, or to affect its safety or effectiveness.

and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a
warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual
property of the third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of TI information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied
by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
