Features & Applications

The LM134/LM234/LM334 are 3-terminal adjustable current sources characterized by: an operating current range of 10000: 1an excellent current regulation wide dynamic voltage range of 1V t 10V

The current is determined by an external resistor without requiring other external components.
Reverse voltages of up to 20V will only draw a current of several microamperes. This enables the circuit to operate as a rectifier and as a source of current in A.C. applications.

For the LM134/LM234/LM334, the voltage on the control pin is 64mV at +25°C and is directly proportional to the absolute temperature (°K). The simplest external resistor connection generates a current with approximately 0.33%/°C temperature dependence. Zero drift can be obtained by adding an additional resistor and a diode to the external circuit.
