The LM4121 is a precision bandgap voltage reference available in a fixed 1.25V and adjustable version with up to 5 mA current source and sink capability.

This series reference operates with input voltages as low as 1.8V and up to 12V consuming 160 µA (Typ.) supply current. In power down mode, device current drops to less than 2 μA.

The LM4121 comes in two grades A and Standard. The best grade devices (A) have an initial accuracy of 0.2%, while the standard have an initial accuracy of 0.5%, both with a tempco of 50ppm/°C ensured from −40°C to +125°C.

The very low operating voltage, low supply current and power-down capability of the LM4121 makes this product an ideal choice for battery powered and portable applications.

The device performance is ensured over the industrial temperature range (−40°C to +85°C), while certain specs are ensured over the extended temperature range (−40°C to +125°C). Please contact Texas Instruments for full specifications over the extended temperature range. The LM4121 is available in a standard 5-pin SOT-23 package.
