1 / 8 page UC19431 UC29431 UC39431 UC39431B DESCRIPTION The UC39431 is an adjustable shunt voltage regulator with 100mA sink ca- pability. The architecture, comprised of an error amplifier and transconductance amplifier, gives the user separate control of the small signal error voltage frequency response along with a fixed linear transconductance. A minimum 3MHz gain bandwidth product for both the error and transconductance amplifiers assures fast response. In addition to external programming, the IC has three internal resistors that can be con- nected in six different configurations to provide regulated voltages of 2.82V, 3.12V, 5.1V, 7.8V, 10.42V, and 12.24V. A sister device (UC39432) provides access to the non-inverting error ampilifer input and reference, while elimi- nating the three internal resistors. Precision Adjustable Shunt Regulator FEATURES • Multiple On-Chip Programmable Reference Voltages • 0.4% Initial Accuracy • 0.7% Overall Reference Tolerance • 2.2V to 36.0V Operating Supply Voltage and User Programmable Reference • 36.0V Operating Supply Voltage • Reference Accuracy Maintained For Entire Range of Supply Voltage • Superior Accuracy and Easier Compensation for Optoisolator Application • Improved Architecture Provides a Known Linear Transconductance with a +5% Typical Tolerance 04/99 BLOCK DIAGRAM UDG-95087 |
