Description  
The LM134/LM234/LM334 are 3-terminal  
adjustable current sources characterized by:  
an operating current range of 10000: 1  
an excellent current regulation  
D
SO-8  
(Plastic micropackage)  
a wide dynamic voltage range of 1V t 10V  
The current is determined by an external resistor  
without requiring other external components.  
Pin connections  
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.  
TO-92  
(Bottom view)  
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.
