General Description
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 A (Typ.)
supply current. In power down mode, device current drops to less than 2 A.
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 guaranteed
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 guaranteed over the industrial temperature range (-40°C to +85°C), while certain
specs are guaranteed over the extended temperature range (-40°C to +125°C). Please contact National for
full specifications over the extended temperature range. The LM4121 is available in a standard 5-pin SOT-23
package.
