Linear Voltage Regulators
Fixed Output
These low cost monolithic circuits provide positive and / or negative regulation at currents from 100 mA to 3.0 A. They are ideal for on-card regulation employing current limiting and thermal shutdown. Low VDiff devices are offered for battery powered systems. Although designed primarily as fixed voltage regulators, these devices can be used with external components to obtain adjustable voltages and currents.

Adjustable Output
Motorola offers a broad line of adjustable output voltage regulators with a variety of output current capabilities. Adjustable voltage regulators provide users the capability of stocking a single integrated circuit offering a wide range of output voltages for industrial and communications applications. The three-terminal devices require only two external resistors to set the output voltage.

Switching Regulator Control Circuits
These devices contain the primary building blocks which are required to implement a variety of switching power supplies. The product offerings fall into three major categories consisting of single-ended and double-ended controllers, plus single-ended ICs with on-chip power switch transistors. These circuits operate in voltage, current or resonant modes and are designed to drive many of the standard switching topologies. The single-ended configurations include buck, boost, flyback and forward converters. The double-ended devices control push-pull, half bridge and full bridge configurations.

MOSFET / IGBT Drivers
High Speed Dual Drivers
These two series of high speed dual MOSFET driver ICs are specifically designed for applications requiring low current digital circuitry to drive large capacitive loads at high slew rates. Both series feature a unique undervoltage lockout function which puts the outputs in a defined low state in an undervoltage condition. In addition, the low "on" state resistance of these bipolar drivers allows significantly higher output currents at lower supply voltages than with competing drivers using CMOS technology. Logic The MC34151 series is pin-compatible with the MMH0026 Input A and DS0026 dual MOS clock drivers, and can be used as drop-in replacements to upgrade system performance. The MC34152 noninverting series is a mirror image of the inverting MC34151 series. These devices can enhance the drive capabilities of first generation switching regulators or systems designed with CMOS / TTL logic devices. They can be used in dc-to-dc Logic Input B converters, motor controllers, capacitor charge pump converters, or virtually any other application requiring high speed operation of power MOSFETs.
