The LM3460 is a monolithic integrated circuit designed for precision control of GTLplus and GTL Bus termination. This controller is available in a tiny SOT23-5 package, and includes an internally compensated op amp, a bandgap reference, an NPN output transistor, and voltage setting resistors. A trimmed precision bandgap voltage reference utilizes temperature drift curvature correction for excellent voltage stability over the operating range. The precision output control enables the termination voltage to maintain tight regulation, despite fast switching requirements on the bus. The LM3460 controller is designed to be used with a high current (> 7A) NPN pass transistor to provide the high current needed for the bus termination. The wide bandwidth of the feedback loop provides excellent transient response, and greatly reduces the output capacitance required, thus reducing cost and board space requirements.
