The LM4121 is a precision bandgap reference voltage available in a fixed and adjustable version of 1.25V with up to 5 mA current supply and sink capability.
This series operates with reference voltages up to 1.8V and up to 12V consuming 160μA (typical) of low supply current. In power-down mode, the device has less than 2μA of current drop in force.
The LM4121 is available in two Grade A and Standards. The best (A) have an initial accuracy of 0.2%, while the standard has a 0.5% initial accuracy both with a 50PPM/°C guaranteed temperature coefficient from -40°C to +125°C for rated devices
The LM4121 capability at very low operating voltages, low supply current, and power-down 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 LM4121 is available in a standard 5-pin SOT-23 package.
