DESCRIPTION
The L7800 series of three-terminal positive
regulators is available in TO-220 TO-220FP TO-3
and D2PAK packages and several fixed output
voltages, making it useful in a wide range of
applications.These regulators can provide local
on-card regulation, eliminating the distribution
problems associated with single point regulation.

ABSTRACT
The aim of this paper is to describe the implementation of a lowpower,low-cost 16-bit RISC microcontroller that will act as thecore of a stand-alone security system. The controller is designedto provide moderate-high security at very low cost and to be ableto operate independent of a database. It is designed using 1.5-mSCMOS process from MOSIS and operates at a frequency of 12.5MHz.

ABSTRACT:

Current mode implementation provides an alternative to high speed data conversion systems for low voltage applications. The pursuing of speed and accuracy of data conversion makes comparator critical. This paper presents a novel switched current (SI) comparator which achieves high speed without sacrificing either accuracy or power dissipation. Employing a class AB cur ....etc

Statistical analysis and predictive modeling is used here as a method for the equipment performance study on voltage regulators. The the number and types
of failure that frequently occured in the different types of single-phase voltage
regulators were determined.The article identifies the type of voltage regulator that showed the maximum number of failures and also type of failures occurred and investigates the reasons for those.

Voltage Regulators
The function of the voltage regulators is to maintain a relatively constant voltag ....etc

Multipliers
Multipliers are among the fundamental components of many digital systems
The largest contribution to the total power consumption in the multiplier is due to the generation of partial product
Among all the multipliers shift and add multipliers are the most commonly used ,due to its simplicity & relatively small area requirement
