Three-terminal regulator

Three-terminal regulators are used in the majority of board-level regulator applieations. They exeel in eost and ease of use for these applieations. They ean also, with eare, be used as the basis or higher funetionality linear regulators. [Pg.15]

This section will be discussed in terms of an example, the LM317. First, it is important to realize that the industry part number or alphanumeric descriptor of the IC regulator is not unique to the manufacturer. The LM317, being a popular three-terminal adjustable regulator is found in several manufacturer s databooks. It certainly could be the case, however, that a particular regulator is supplied by only one manufacturer. Some manufacturers provide a cross reference guide in the data book to aid in substitution or replacement decisions. [Pg.1040]

To quickly check the junction temperature [Eq. (10.66)] use the 9ja value from the data sheet and the calculated power dissipated for the circuit specihc regulator application. (Note the power calculation may be a simple matter, as in the case of a three-terminal voltage regulator [ ( Vin — Vbur) x /out] J or it maybe more difficult, as in the case of a pulsed input or highly reactive loads. This is considered to be beyond the scope of this work.) If the maximum ambient temperature is not known, it is best to measure it. If that is not possible, an estimate may be made considering the operating environment. In open air, 50°C is not a bad number but in a closed encasement with other electronics, 60°C maybe more reasonable. Automotive and some plant environments are more severe (70-75°C). [Pg.1041]
