Alternatively, a shield foil can be laid out on the 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 datashest DC leakages. Its long-term stability is typically 3 to 10 ppm per hours when held near Tmax, and slightly better when operated at room temperature.

Do not connect anything to these pins, or improper operation may result.

LM – LM part cross-reference datasheet –

To avoid this transient, it may be advisable to preload the output with a few milliamperes of load to ground. The LM is recommended for applications where the highest stability and lowest noise is required over the full military temperature range. Capacitance in the Typical Performance Characteristics section show graphically that a modest capacitance of 0.

The LM also provides excellent stability vs.

This datasheet has been downloaded from: Unless otherwise noted, these conditions apply: There is no lj607 that the Specified Temperatures are exactly at the minimum or maximum deviation. They are based on a buried zener reference as pioneered in the LM references, but do not require any heater, as they rely on special temperature-compensation techniques Patent Pending.


Ceramic capacitors may seem to do the job, but are not recommended for production use, as the high-K ceramics cannot be guaranteed for low leakage, and may exhibit piezo-electric effects, converting vibration or datashset stress into excessive electrical noise.

The output has a class-B stage, so if the load current changes from sourcing to sinking, an output transient will occur. In some applications it may be advantageous to pre-load the output to either Vin or to ground, to avoid this crossover point.

The devices have a 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.

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.

The LM is suitable for limited-temperature operation. Changes in output voltage due to heating effects are covered under the specifications for Thermal Regulation and Tempco. For example, dahasheet the output were trimmed up to 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 xatasheet capacitance could couple noises into the output.

These limits are not to be used to calculate outgoing quality levels. Contact the factory for availability of devices with proven long-term stability. Documents Flashcards Grammar checker.

The output can sink current as well as daatasheet it, but the output impedance is much better for sourcing current. The device does not include a thermal shut-down circuit. 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. This point occurs when the device is required to sink approximately 1. Pin numbers for H, M or N packages. These pins may be cut off if desired. However, avoid overloads at high ambient temperatures, as a prolonged short-circuit may cause the junction temperature to exceed the Absolute Maximum Temperature.


LM see curve above: The capacitor used should be a low-leakage type.

Tsimshatsui, Kowloon Hong Kong Tel: Regulation is measured at constant temperature using pulse testing with a low duty cycle.

Avoid such overloads for voltages higher than a 20 V, for more than 5 seconds, or, at high ambient temperatures. If the output is pulled to a positive voltage such as a 15 or a 20V, the output current will be limited, but overheating may occur.

In Sinking mode, connect 0. Trimming to a wider range is possible, but is not recommended as it may degrade the Tempco and the Tempco linearity at temperature extremes. 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 datashewt labeling, can be reasonably expected to result in a significant injury to the user.

The LM has a Class B output, and will exhibit transients at the crossover point. National Semiconductor Europe Fax: Thermal regulation is defined as datasheeg change in the output voltage at a time T after a step change of power dissipation of mW.
