DESCRIPTION  
The LM134/LM234/LM334 are 3-terminal adjust-  
able current sources characterized by :  
- an operatingcurrent 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.

(Plastic Micropackage)  
Reverse voltages of up to 20V will only draw a cur-  
rent of several microamperes. This enables the  
circuit tooperate asa rectifierandasa sourceofcur-  
rent in a.c. applications.  
ORDER CODES  
For the LM134/LM234/LM334, the voltage on the  
control pin is 64mV at +25oC and is directly propor-  
tionaltotheabsolutetemperature(oK). The simplest  
external resistor connection generates a current  
with 0.33%/oC temperature dependence. Zero  
drift can be obtainedbyaddinganadditionalresistor  
and a diode to the external circuit.
