LM334 数据手册 ( 数据表 ) - 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.

FEATUREs
■ Operates from 1V to 40V
■ 0.02%/V current regulation
■ Programmable from 1µA to 10mA
■ ±3% initial accuracy
