In some applications it may be advantageous datwsheet pre-load the output to either Vin or to ground, to avoid this crossover point.
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. 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. Unless otherwise noted, these conditions apply: Pin numbers for H, M or N packages. Documents Flashcards Grammar checker.
LM see curve above: The curves showing the Noise vs. The output can sink current as well as source it, but the output impedance is much better for sourcing current.
Do not connect anything datashete these pins, or improper operation may result.
Contact the factory for availability of devices with proven long-term stability. Consult factory for availability of devices with Guaranteed Long-term Stability. For example, if the output datasyeet trimmed up to The capacitor used should be a low-leakage type. However, avoid overloads at high ambient temperatures, as a prolonged short-circuit may cause the junction temperature to exceed the Absolute Maximum Temperature.
Changes in output voltage due to heating effects are covered under the specifications for Thermal Regulation and Tempco. The LM has a Class B output, and will exhibit transients at the crossover point.

Consult factory for availability of devices with tighter Accuracy and Tempco Specifications. These pins may be cut off if desired. Capacitance in the Typical Performance Characteristics section show graphically that a modest capacitance of 0. In Sinking mode, connect 0. 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 is recommended for applications where the highest stability and lowest noise is required over the full military temperature range. Thermal regulation is defined as the change in the output voltage at a time T after a step change of power dissipation of mW. The devices have a 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.
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.

Avoid such overloads for voltages higher than a 20 Lj607, for more than km607 seconds, or, at high ambient temperatures. A trim pin datassheet available which permits fine-trimming of Vout, and also permits filtering to greatly decrease the output noise by adding a small capacitor 0.
Tsimshatsui, Kowloon Hong Kong Tel: The output has a class-B stage, so if the load current changes from sourcing to sinking, an output transient will occur. Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Trimming to a wider range is possible, but is not recommended as it may degrade the Tempco and the L6m07 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 datashet into the output.
Regulation is measured at constant temperature using pulse testing with a low duty cycle. The LM is suitable for limited-temperature operation. This datasheet has been downloaded from: 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.
Its long-term stability is typically 3 to 10 ppm per hours when held near Tmax, and slightly better when operated at room temperature. The trim scheme is such that ln607 resistors are cut open rather than being trimmed partially cutto avoid resistor drift caused by electromigration in the trimmed area. The output is short-circuit-proof to ground.
National Semiconductor Europe Fax: 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. A military RETS electrical test specification is available on request.
The LM also provides excellent stability vs. l,607

Lmm607 limits are not to be used to calculate outgoing quality levels. To avoid this transient, it may be advisable to preload the output with a few milliamperes of load to ground. This point occurs when the device is required to sink approximately 1. There is no guarantee that the Specified Temperatures are exactly at the minimum or maximum deviation.
