a
precision bandgap voltage  
Low Voltage Operation  
High Output Voltage Accuracy: 0.2%  
Source and Sink Current Output: ±5 mA  
Supply current: 160 μA Typ.  
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.  
Low Temperature Coefficient: 50 ppm/°C  
Enable Pin  
Output Voltages: 1.25V and Adjustable  
Industrial Temperature Range: −40°C to +85°C  
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.  
(For Extended Temperature Range, −40°C to  
125°C, Contact Texas Instruments)  
APPLICATIONS  
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.
