If adequate heat sinking is provided, they can deliver over 1. They are intended as fixed voltage regulators in a wide range of applications including local on-card regulation for elimination of noise and distribution problems associated with single-point regulation. In addition to use as fixed voltage regulators, these devices can be used with external components to obtain adjustable output voltages and currents. PDF , 3. Extract from the document. PDF , Kb , Revision: B , File published: May 6, Of all common environmental parameters humidity is perhaps the least understood and most difficult tomeasure.

The most common electronic humidity detection methods albeit highly accurate are not obviousand tend to be expensive and complex See Box.

Accurate humidity measurement is vital to a number ofdiverse areas including food processing paper and lumber production pollution monitor. PDF , 75 Kb , File published: May 8, The power limitations of the physical packaging for a linear regulator device can limit the total output current or the input-to-output voltage differential. This inherent limitation is not always apparent from the product data sheet and must be evaluated during the design phase. This application note shows how the package can limit the operating envelope of a linear regulator.

PDF , Kb , Revision: B , File published: May 6, This application note provides information and examples of isolation techniques for signal conditioning. In spite of this limitation their ease of use low cost and full on-chip overload protection have generated wide acceptance. Now with the introduction of the LM it is possible to use a single regulator for any output voltage from 1. Selecting close-tolerance outp. PDF , Kb , Revision: B , File published: May 5, This application report discusses how a super matched bipolar transistor pair sets new standards for driftand noise.

The LM regulators are complete 3-terminal regulators requiring no external components fornormal operation. However by adding a few parts one may improve the transient response provide for avariable output voltage or increase the output current. Included on the chip are all of t. Each section includes an example to increase the understandab. PDF , Kb , Revision: A , File published: May 5, When working with voltage regulator circuits the designer is often confronted with the need to calculatethe tolerance of the regulated output voltage.

For fixed voltage regulators this problem is easily managedbecause the required information is directly supplied on the semiconductor manufacturer's data sheet. Privacy Policy Change Privacy Settings. Texas Instruments.
