3-Terminal Adjustable Current Source
LM134/LM234/LM334
3-Terminal Adjustable Current Sources
General Description

The LM134/LM234/LM334 are 3-terminal adjustable current
sources featuring 10,000:1 rangein operating current, excel-
lent current regulation anda wide dynamic voltage rangeofto 40V. Currentis established with one external resistor
andno other parts are required. Initial current accuracyis
±3%. The LM134/LM234/LM334 are true floating current
sources withno separate power supply connections.In ad-
dition, reverse applied voltagesofupto 20Vwill draw onlya
few dozen microamperesof current, allowingthe devicesto
actas botha rectifier and current sourceinAC applications.
The sense voltage usedto establish operating currentinthe
LM134is 64mVat 25˚C andis directly proportionalto abso-
lute temperature (˚K). The simplest one external resistor
connection, then, generatesa current with ≈+0.33%/˚C tem-
perature dependence. Zero drift operation canbe obtained adding one extra resistor anda diode.
Applicationsfor the current sources include bias networks,
surge protection, low power reference, ramp generation,
LED driver, and temperature sensing. The LM234-3 and
LM234-6 are specifiedas true temperature sensors with
guaranteed initial accuracyof ±3˚C and ±6˚C, respectively.
These devices are idealin remote sense applications be-
cause series resistancein long wire runs does not affect
accuracy.In addition, only2 wires are required.
The LM134is guaranteed overa temperature rangeof
−55˚Cto +125˚C,the LM234 from −25˚Cto +100˚C andthe
LM334 from 0˚Cto +70˚C. These devices are availablein
TO-46 hermetic, TO-92 and SO-8 plastic packages.
