LM3460-1.2, -1.5
Precision Controller for GTLp and GTL Bus Termination
General Description
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 in-
cludes an internally compensated op amp, a bandgap refer-
ence, an NPN output transistor, and voltage setting resistors.
A trimmed precision bandgap voltage reference utilizes tem-
perature drift curvature correction for excellent voltage stabil-
ity over the operating range. The precision output control en-
ables 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 cur-
rent 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.

MARKING CODE: The first letter
″D″ identifies the part as a Driver, and the next two numbers define the voltage for the part. The fourth letter indicates the
grade, with
″A″ designating the prime grade of product.
AVAILABILITY: The SOT23-5 package is only available in quantity of 1000 on tape and reel (designated by the letters
″M5″ in the part number), or in quantity
of 3000 on tape and reel (indicated by the letters
″M5X″ in the part number).
