The LM79LXXAC series of 3-terminal negative

2• Preset Output Voltage Error is Less than ±5% voltage regulators features fixed output voltages of

Over Load, Line and Temperature −5V, −12V, and −15V with output current capabilities

• Specified at an Output Current of 100mA in excess of 100mA. These devices were designed

• Easily Compensated with a Small 0.1μF Output using the latest computer techniques for optimizing

the packaged IC thermal/electrical performance. The

Capacitor LM79LXXAC series, when combined with a minimum

• See AN-1112 (SNVA009) for DSBGA peak output current limiting, and a thermal shutdown

Considerations circuit to prevent excessive junction temperature.

Although designed primarily as fixed voltage

regulators, these devices may be combined with

simple external circuitry for boosted and/or adjustable

voltages and currents. The LM79LXXAC series is

available in the 3-lead TO package, the 8-lead SOIC

package, and the 6-Bump DSBGA package.

For output voltages other than the pre-set -5V, -12V

and -15V, the LM137L series provides an adjustable

output voltage range from -1.2V to -47V.

(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. 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) 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)

(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.

(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.
