illustrate
The LM4120 is a low-dropout, high-accuracy, low-power bandgap, output current source of up to 5 mA, and voltage reference for absorption capacity.
This series of operations is based on input voltages up to 2V and up to 12V consumes a low supply current of 160μA (typical). In power-down mode, the device has less than 2μA of current drop.
The LM4120 is available in two grades (A, standard) and seven voltage options for greater flexibility. The best (A) has an initial accuracy of 0.2%, while the standard has an initial accuracy of 0.5% both with a 50PPM/°C guaranteed temperature coefficient from -40°C to +125°C, graded equipment
The LM4120's ability to lose power at very low dropouts, low supply current, and power off makes this product ideal for battery-powered and portable applications.
The performance of the device is guaranteed in the industrial temperature range (-40°C to +85°C), while some specifications are in the extended temperature range (-40°C to +125°C). For full specifications, please contact the country in the extended temperature range. The LM4120 is available in a standard 5-pin SOT-23 package.
