| 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. 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.Operates from 1V to 40V Programmable from 1μA to 10mA 0.02%/V current regulation ±3% initial accuracy More information: | | Control Method: | Current | Mounting Type: | Surface Mount | Package Type: | SO | Pin Count: | 8 | Dimensions: | 5 x 4 x 1.5mm | Length: | 5mm | PWM Controller Type: | Current Mode | Width: | 4mm | Height: | 1.5mm | Maximum Operating Supply Voltage: | 40 V | Maximum Operating Temperature: | +100 °C | Minimum Operating Supply Voltage: | 1 V | Minimum Operating Temperature: | -25 °C |
