LM334(2003) Datasheet - 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 t 10V
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.c. applications.

■ OPERATES FROM 1V TO 40V
