In most electronic systems, some form of voltageregulation is required. In the past, the task of voltageregulator design was tediously accomplished with discretedevices, and the results were quite often complex and , with bipolar monolithic regulators, this task has beensignificantly simplified.

3 The designer now has a wide choiceof fixed, low VDiff and adjustable type voltage devices incorporate many built in protectionfeatures, making them virtually immune to the catastrophicfailures encountered in older discrete switching Power Supply continues to increase inpopularity and is one of the fastest growing markets in theworld of Power conversion. They offer the designer severalimportant advantages over linear series pass advantages include significant advancements in theareas of size and weight reduction, improved efficiency, andthe ability to perform voltage step up, step down, andvoltage inverting functions. Motorola offers a diverseportfolio of full featured switching regulator control circuitswhich meet the needs of today s modern compact supplies, MPU/MCU based systems, industrialcontrols, computer systems and many other productapplications are requiring Power supervisory functionswhich monitor voltages to ensure proper system offers a wide range of Power supervisory circuitsthat fulfill these needs in a cost effective and efficientmanner.

4 MOSFET drivers are also provided to enhance thedrive capabilities of first generation switching regulators orsystems designed with CMOS/TTL logic devices. Thesedrivers can also be used in dc to dc converters, motorcontrollers or virtually any other application requiring highspeed operation of Power Master Selection GuideAnalog and Interface Integrated 2 Linear Voltage RegulatorsFixed OutputThese low cost monolithic Circuits provide positive and/ornegative regulation at currents from 100 mA to A. They areideal for on card regulation employing current limiting andthermal shutdown. Low VDiff devices are offered for batterypowered designed primarily as fixed voltage regulators,these devices can be used with external components to obtainadjustable voltages and 1.
