LM234(1997) Datasheet PDF - STMicroelectronics

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 tooperate asa rectifierandas a sourceof current in a.c. applications.

■ OPERATES from 1V to 40V
■ 0.02% V CURRENT REGULATION
■ PROGRAMMABLE from 1µA to 10mA
■ ±3% INITIAL ACCURACY
