OPERATES from 1V to 40V 0.
02% V CURRENT REGULATION PROGRAMMABLE from 1µA to 10mA ±3% INITIAL ACCURACY Z TO92 (Plastic Package) DESCRIPTION The LM134/LM234/LM334 are 3-terminal adjustable 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 current of several microamperes.
This enables the circuit to operate as a rectifier and as a source of current in a.
