LM134-LM234-LM334

Three terminal adjustable current sources

Features

■ Operates from 1V to 40V

■ 0.02%/V current regulation

■ Programmable from 1µA to 10mA

■ ±3% initial accuracy

TO-92

(Plastic package)

Description

The LM134/LM234/LM334 are 3-terminal

adjustable current sources characterized by:

■ an operating current range of 10000: 1

■ an excellent current regulation

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.

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.
