APPLICATION INFORMATION
PROGRAMMING OUTPUT VOLTAGE
(Selecting R1 and R2 as shown in Figure 18)
The LM2825 is available in two adjustable output versions. The LM2825-ADJ has been optimized for output
voltages between 1.23V and 8V, while the LM2825H-ADJ covers the output voltage range of 7V to 15V. Both
adjustable versions are set in the following way.
(1)
Select a value for R1 between 240Ω and 1.5 kΩ. The lower resistor values minimize noise pickup at the sensitive
adjust pin. (For lowest temperature coefficient and the best stability with time, use 1% metal film resistors.)
Select R2 with the following equation.
(2)
When programming VOUT, keep in mind that VIN must be greater than VOUT + 2V for proper operation.
OPTIONAL EXTERNAL COMPONENTS
SOFT-START CAPACITOR
CSS: A capacitor on this pin provides the regulator with a Soft-start feature (slow start-up). The current drawn
from the source starts out at a low average level with narrow pulses, and ramps up in a controlled manner as the
pulses expand to their steady-state width. This reduces the startup current considerably, and delays and slows
down the output voltage rise time.
It is especially useful in situations where the input power source is limited in the amount of current it can deliver,
since you avoid loading down this type of power supply.
Under some operating conditions, a Soft-start capacitor is required for proper operation. Figure 19 indicates the
input voltage and ambient temperature conditions for which a Soft-start capacitor may be required.
This curve is typical for full ensured output current and can be used as a guideline. As the output current
decreases, the operating area requiring a Soft-start capacitor decreases. Capacitor values between 0.1 μF and 1
μF are recommended. Tantalum or ceramic capacitors are appropriate for this application.
INPUT CAPACITOR
CIN: An optional input capacitor is required if the package is more than 6″ away from the main filter or bypass
capacitor. A low ESR aluminum or tantalum bypass capacitor is recommended between the input pin and ground
to prevent large voltage transients from appearing at the input. In addition, to be conservative, the RMS current
rating of the input capacitor should be selected to be at least ½ the DC load current. With a 1A load, a capacitor
with a RMS current rating of at least 500 mA is recommended.
The voltage rating should be approximately 1.25 times the maximum input voltage. With a nominal input voltage
of 12V, an aluminum electrolytic capacitor (Panasonic HFQ series or Nichicon PL series or equivalent) with a
voltage rating greater than 15V (1.25 × VIN) would be needed.
Solid tantalum input capacitors should only be used where the input source is impedance current limited. High
dV/dt applied at the input can cause excessive charge current through low ESR tantalum capacitors. This high
charge current can result in shorting within the capacitor. It is recommended that they be surge current tested by
the manufacturer.The TPS series available from AVX, and the 593D series from Sprague are both surge current
tested.
Use caution when using ceramic capacitors for input bypassing, because it may cause ringing at the VIN pin.

SNVS127C – MAY 1997 – REVISED APRIL 2013
LOWERING OUTPUT RIPPLE
When using the adjustable parts, one can achieve lower output ripple voltage by shorting a resistor internal to the
LM2825. However, if this resistor is shorted, a feed forward capacitor must be used to keep the regulator stable.
For this reason, this resistor must be left open on all of the fixed output voltage versions or instability will result.
See the FEED FORWARD CAPACITOR SELECTION (CFF) selection below. Shorting the internal resistor is
accomplished by shorting pins 8 and 9 on the LM2825, and will typically reduce output ripple by 25 to 33%.
FEED FORWARD CAPACITOR SELECTION (CFF)
When using an adjustable part and pins 8 and 9 are shorted to reduce output ripple, a feed forward capacitor is
required. This capacitor is typically between 680 pF and 2700 pF. Table 1 shows the value for CFF for a given
output voltage and feedback resistor R2 (R1 = 1 kΩ).

THERMAL CONSIDERATIONS
The LM2825 is available in a 24-pin through hole PDIP. The package is molded plastic with a copper lead frame.
When the package is soldered to the PC board, the copper and the board are the heat sink for the LM2825.

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. 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.

Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license 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 significant portions 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. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
