Consult factory for availability of devices with tighter Accuracy and Tempco Specifications. The LM is suitable for limited-temperature operation. 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. Unless otherwise noted, these conditions apply: This point occurs when the device is required to sink approximately 1. Documents Flashcards Grammar checker. The capacitor used should be a low-leakage type.
The LM also provides excellent stability vs. 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. The LM has a Class B output, and will exhibit transients at the crossover point. Contact the factory for availability of devices with proven long-term stability.
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. In some applications it may be advantageous to pre-load the output to either Vin or to ground, to avoid this crossover point. Pin numbers for H, M or N packages.
There is no guarantee that the Specified Temperatures are exactly at the minimum or maximum deviation. Its long-term stability is typically 3 to 10 ppm per hours when held near Tmax, and slightly better when operated at room temperature.
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 device does not include a thermal shut-down circuit. However, avoid overloads at high ambient temperatures, as a prolonged short-circuit may cause the junction temperature to exceed the Absolute Maximum Ddatasheet.
The output is short-circuit-proof to ground. 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 and DC leakages.
These limits datahseet not to be used to calculate outgoing quality levels. The devices have a Datashedt Maximum Ratings indicate limits beyond which damage to the device may occur.
The output can sink current as well as source it, but the output impedance is much better for sourcing current. LM see curve above: In Sinking mode, connect 0. Capacitance in the Typical Performance Characteristics section show graphically that a modest capacitance of 0.
Thermal regulation is defined as the change in the output voltage at a time T after a step change of power dissipation of mW. Do not connect anything to these pins, or improper operation may result. Changes in output voltage due to heating effects are covered under the specifications for Thermal Regulation and Tempco.
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.
The trim pin pin 5 should also be guarded away from noise ,m607 and leakages, as it has a sensitivity of 15 millivolts of DVout per microampere. Trimming to a wider range is possible, but is not recommended as it may degrade the Tempco and the Tempco linearity at temperature extremes.

Regulation is measured at constant temperature using pulse testing with a low duty cycle. To avoid this transient, it may be datashee to preload the output with a few milliamperes of load to ground. For example, if the output were trimmed up to 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. National Semiconductor Europe Fax: This datasheet has been downloaded from: 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 datasheer effects, converting vibration or mechanical stress into excessive electrical noise.
The curves showing the Noise vs. A military RETS electrical test specification is available on request. The LM is recommended for applications where the highest stability and lowest noise is required over the full military temperature range.

Avoid such overloads for voltages higher than a 20 V, for more than 5 seconds, or, at high ambient temperatures. The output has a class-B stage, so if the load current changes from sourcing to sinking, an output transient will occur.
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 pm607 reasonably expected to result in a significant injury to the user.
These pins may be cut off if desired.
