Consult datasbeet for availability of datashewt with tighter Accuracy and Tempco Specifications. 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.

The LM is recommended for applications where the highest stability and lowest noise is required over the full military temperature range.

To avoid this transient, it may be advisable to preload the output with a few milliamperes of load to ground. The output is short-circuit-proof to ground. The capacitor used should be a low-leakage type. 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. The output can sink current as well as source it, but the output impedance is much better for sourcing current.

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 mechanical stress into excessive electrical noise. Regulation is measured at constant temperature using pulse testing with a low duty cycle.


LM see curve above: Capacitance in the Typical Performance Characteristics section show graphically that a modest capacitance of 0. For example, if the output were trimmed up to Thermal regulation is defined as the change in the output voltage at a time T after a step change of power dissipation of mW. A military RETS electrical test specification is available on request. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur.

The devices have a 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.

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 signals and leakages, as it has a sensitivity of 15 millivolts of DVout per microampere.

Changes in output voltage due to heating effects are covered under the specifications for Thermal Regulation and Tempco. 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. There is no guarantee that the Specified Temperatures are exactly at the minimum or maximum deviation. 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. Trimming to a wider range is possible, but is not recommended as it may degrade the Tempco and the Tempco linearity at temperature extremes. The LM is suitable for limited-temperature operation.

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. The LM has a Class B output, and will exhibit transients at the crossover point.

Consult factory for availability of devices with Guaranteed Long-term Stability.

Unless otherwise noted, these conditions apply: Its long-term stability is typically 3 to 10 ppm per hours when held near Tmax, and slightly better when operated at room ml607. This point occurs when the device is required to sink approximately 1.

Datashewt limits are not to be used to calculate outgoing quality levels. 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.

However, avoid overloads at high ambient temperatures, as a prolonged short-circuit may cause the junction temperature to exceed the Absolute Maximum Temperature. The curves showing the Noise vs. Do not connect anything to these pins, or improper operation may result.

Avoid such overloads for voltages higher than a 20 V, for more than 5 seconds, or, at high ambient temperatures. Contact the factory for availability of devices with proven long-term stability.
