5、sment for electronic components. Blank detail specification: Integrated voltage regulators”. Terminology and conventions. The text of the CECC specification has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identic
6、al with those used in British Standards; attention is drawn especially to the following. The comma has been used as a decimal marker. In British Standards it is current practice to use a full point on the baseline as the decimal marker. Cross-references. The British Standard which implements CECC 00
7、100 is BS 9000 “General requirements for a system for electronic components of assessed quality” Part 2 “Specification for national implementation of CECC basic rules and rules of procedure”. Scope. This standard lists the ratings, characteristics and inspection requirements which shall be included
8、as mandatory requirements in accordance with BS CECC 90000 in any detail specification for these devices. Detail specification layout. The front page layout of detail specifications released to BS CECC family or blank detail specifications will be in accordance with BS 9000 Circular Letter No. 15. A

14、 System for electronic components of assessed quality. The object of the System is to facilitate international trade by the harmonization of the specifications and quality assessment procedures for electronic components, and by the grant of an internationally recognized Mark, or Certificate, of Conf
15、ormity. The components produced under the System are thereby accepted by all member countries without further testing. This specification has been formally approved by the CECC, and has been prepared for those countries taking part in the System who wish to issue national harmonized specifications f
16、or INTEGRATED VOLTAGE REGULATORS. It should be read in conjunction with the current regulations for the CECC System. At the date of printing of this specification the member countries of the CECC are Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the Netherlands, Norway, Portug
17、al, Spain, Sweden, Switzerland, and the United Kingdom. Preface This blank detail specification (BDS) was prepared by CECC WG9 “INTEGRATED CIRCUITS”. It is based, wherever possible, on the Publications of the International Electrotechnical Commission and in particular on IEC 147: Essential ratings a
18、nd characteristics of semiconductor devices and general principles of measuring methods. The text of this BDS was circulated to the CECC for voting in the documents listed below and was ratified by the President of the CECC for printing as a CECC Specification. It is recognized that the layout propo
19、sed cannot apply to all detail specifications based on this document. For example when several similar devices are covered by the same detail specification. It may be convenient to give the limiting values in a table. DocumentsDate of votingReport on the voting CECC (Secretariat) 882December 1979CEC
