LM134Z Datasheet PDF - ST Microelectronics

●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
