Information is also supplied on heat sink selection and design, power transformer filter and specification, and on various extended use applications for the basic three-terminal and dual tracking regulators. If a system supply already exists and regulation is required at a current range or voltage listed in Figure 1.2, selection is relatively easy. Make initial selection from Figure 1 .2 and the data sheet summary in Section 2, then go directly to the product selection procedures of Section 3. If a higher current is required, refer also to Section 7, Applications, for current booster circuits. Where a heat sink is required (possible with K, T & P suffix devices), refer to Sections 5 and 6 on heat sink selection and design. For small systems using only one regulator or if a system supply does not yet exist. Section 8, Power Supply Design, provides the information necessary to specify transformer output voltage and current, diode characteristics, and filter capacitance. For applications other than simple three-terminal regulation (listed in Section 1 .3), refer to Section 7, Applications. For voltage regulation at other than the voltages listed in Figure 1.2, refer to the applications section, or consider an adjustable regulator such as the LM105, LM723, LM1 17, etc. Refer to the data sheets on these parts and to the National Semiconductor Linear Applications Handbook. Section 1.4 compares the features and applications of three-terminal and adjustable regulators. Ordering information is covered in Appendix 2. Test methods and circuits are covered in Appendix 4. A cross-reference listing the National Semiconductor part number most closely matching other manufacturers' part numbers is in Appendix 6. 1.2 FEATURES OF ON-CARD REGULATION The trend in voltage regulation is toward localized regulation with smaller, low-cost, low-current, fixed-voltage IC regulators which require minimal or no heat sinking and few or no external components. In the past, one used bulky, high power regulators or regulators made up of many discrete components to regulate a line which supplied all areas of an electronic system. Unfortunately, the impedance of this line and associated connectors caused voltage drops which varied throughout the system. Also, any common impedance in the line between chasses or cards could allow unwanted coupling between critical parts of the system. These older systems often required considerable bypassing or decoupling which caused degraded local regulation. More recently, simple three-terminal regulators supplying one to three amps have been placed on individual cards within a system. These, however, are often larger in capacity and price than is necessary for one-per-card use. If used to supply several cards and fully loaded, some of the same old problems recur. The newest regulator designs emphasize low-current ranges and small, low-power, three- lead packages. These regulators are available in a variety of positive and negative voltages at current ranges of 100 mA to 5 A, some in packages as small as the TO-92 plastic small-signal transistor. There are also dual tracking ±100 mA regulators in TO-100 or plastic power DIP packages. With this variety to choose from, it is now possible to select the regulator for each application, and reduce cost significantly over competing approaches. 1-1 H H K,KC, K STEEL N TO-39 TO- 100 TO-3 DIP P TO-202 & TO-92 FIGURE 1.2.

    Electronic Circuits 10CS32 UNIT – 7: Linear Power Supplies, Switched mode Power Supplies 7.1 Regulated power supply The regulated power supply converts the standard 220 volts, 50 or 60 Hz AC available at wall outlets into a constants DC voltage. It is one of the most common electronics circuits that we can find. The DC voltage produce by a power supply is used to power all the types of electronic circuits, such that television receiver, stereo system, CD players and laboratory equipment. The regulated dual voltage DC power supply is to be used for the FM receiver. Two regulators, one positive and the other negative, provide the positive voltage required for the receiver circuits and the dual polarity voltage for the op-amp circuits. The regulated power supply is to provide the necessary dc voltage and current, with low levels of ac ripple and with stability and regulation. There are various methods of achieving a stable dc voltage from ac mains. The two methods are more commonly used. These are used; (i) a linear voltage regulator and (ii) A switching mode regulator. Several types of both linear and switching regulators are available in integrated circuit (IC) form. By using the linear voltage regulator method, we must get the regulated dual dc power supply.

  • Voltage Regulators

    Voltage Regulators

    DATASHEET VOLTAGE REGULATORS VOLTAGE REGULATOR CIRCUIT DATA Regulators provide a power source which remains very close to a fixed value, independent of the load placed on it, provided that the current drawn doesn't exceed the rating of the device. Note: The mini- mum and maximum output voltage specifications for fixed voltage reg- ulators indicate the values which can be expected with variations in load on the device. The same specifications for adjustable regulators indicate the range of voltage output which can be achieved through external componentry. Basic 1A regulated circuit with fixed regulator The 78xx series of voltage regulators require the input pin to be at least 2.5 volts above the output voltage. When a bridge rectifier is used, the DC voltage before the regulator is going to be 1.414 x the AC secondary voltage of the transformer. For good regulation ensure FIXED VOLTAGE REGULATORS that there is at least 3 volts on the input pin over and above the output Polarity Output Voltage Max. Output voltage of the regulator.

    Release 9.2, 31 May 2000 Copyright © 1985-2000 Cadence Design Systems, Inc. The PSpice Library List What is the Library List? The PSpice Library List is an online listing of all of the parts contained in the libraries that are supplied with PSpice. Every part listed has a corresponding PSpice model. The listings are categorized into the following groups: Analog Digital Mixed Signal General devices General devices General devices Japanese devices TTL devices European devices The listings are divided into columns, like a spreadhseet, and show the following information about each device: Device Type Generic Name Part Name Part Library Mfg. Name Tech Type The type of device The generic or The name of the The name of the The name of the The technology type (transistor, diode, standard industry part in the PSpice PSpice library the manufacturer of the of the device (TTL, etc.). name of the device. library. part is stored in. device. ECL, etc.), where applicable. Each group is arranged alphabetically by Device Type. How do I use the Library List? Accessing a library To access a particular library list, simply click on the bookmark for the group and device type you are interested in. (Bookmarks are shown in the left-hand column of this Acrobat Reader page. If you do not see the left-hand column for the bookmarks in Acrobat Reader, choose Bookmarks and Page from the View menu.) Searching for a name To search for a specific part name, library name, or any other text, use Acrobat Reader's built-in Find function.
