1 / 10 page Z TO92 (Plastic Package) . OPERATES from 1V to 40V . 0.02% V CURRENT REGULATION . PROGRAMMABLE from 1 µA to 10mA .± 3% INITIAL ACCURACY DESCRIPTION The LM134/LM234/LM334 are 3-terminal adjust- able current sources characterized by : - an operating current range of 10000 : 1 - an excellent current regulation - a wide dynamic voltage range of 1V to 40V The current is determined by an external resistor without requiring other external components. Reverse voltages of up to 20V will only draw a cur- rent of several microamperes. This enables the circuit to operate as a rectifier and as a source of cur- rent in a.c. applications. For the LM134/LM234/LM334, the voltage on the control pin is 64mV at +25 oC and is directly propor- tional to the absolute temperature ( oK). The simplest external resistor connection generates a current with ≈ 0.33%/oC temperature dependence. Zero drift can be obtainedby adding an additionalresistor and a diode to the external circuit.
