The trim scheme is such that individual resistors are cut open rather than being trimmed partially cutto avoid resistor drift caused by electromigration in the trimmed area.
In some applications it may be advantageous to pre-load the output to either Vin or to ground, to avoid this crossover point.
Trimming to a wider range is possible, but is not recommended as it may degrade the Tempco and the Tempco linearity at temperature extremes. These pins would not be damaged by a short to ground, or by Electrostatic Discharges; however, keep them away from large transients or AC signals, as stray capacitance could couple noises into the output.
National Semiconductor Europe Fax: The LM is recommended for applications where the highest stability and lowest noise is required over the dahasheet military temperature range. These limits are not to be used to dataseet outgoing quality levels. The LM is suitable for limited-temperature operation.
Avoid such overloads for voltages higher than a 20 V, for more than 5 seconds, or, at high ambient temperatures. Capacitance in the Typical Performance Characteristics section show graphically that a modest capacitance of 0. The capacitor used should be a low-leakage type.

Alternatively, a shield foil can be laid out on datashee printed circuit board, surrounding these pins and pin 5, and this guard foil can be connected to ground or to Vout, effectively acting as a guard against AC coupling and DC leakages. This datasheet has been downloaded from: The curves showing the Noise vs.
A military RETS electrical test specification is available on request. Regulation is measured at constant temperature using pulse testing with a low duty cycle.
Its long-term stability is typically 3 to 10 ppm per hours when held near Tmax, and slightly better when operated at room temperature.
Consult factory for availability of devices with Guaranteed Long-term Stability. Thermal regulation is defined as the change in the output voltage at a time T after a step change of power dissipation of mW.
These pins may be cut off if desired.
Pin numbers for H, M or N packages. The output is short-circuit-proof to ground. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Do not connect anything to these pins, or improper operation may result.
This point occurs when the device is required to sink approximately 1. LM see curve above: The device does not include a thermal shut-down circuit. Contact the factory for availability of devices with proven long-term stability. Life support devices or systems are devices or systems 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.
The LM also provides excellent stability vs. The devices have a Tsimshatsui, Kowloon Hong Kong Tel: To avoid this transient, it may be advisable to preload the output with a few milliamperes of load to ground. Changes in output voltage due to heating effects are covered under the specifications for Thermal Regulation and Tempco. Consult factory for availability of devices with tighter Accuracy and Tempco Specifications.

The trim pin pin 5 should also be guarded away from noise signals and leakages, as it has a sensitivity of 15 millivolts of DVout per microampere. In Sinking mode, connect 0. A trim pin is available which permits fine-trimming of Vout, and also permits filtering to greatly decrease the output noise by adding a small capacitor 0.
