LM4120  
Precision Micropower Low Dropout Voltage Reference  
General Description  
The LM4120 is a precision low power low dropout bandgap  
voltage reference with up to 5 mA output current source and  
sink capability.

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

n Fixed output voltages:  
and 5.0V  
n Industrial temperature Range:  
The LM4120 comes in two grades (A and Standard) and  
seven voltage options for greater flexibility. The best grade  
devices (A) have an initial accuracy of 0.2 , while the stan-  
dard have an initial accuracy of 0.5 , both with a tempco of  
50ppm/˚C guaranteed from −40˚C to +125˚C.

The very low dropout voltage, low supply current and  
power-down capability of the LM4120 makes this product an  
ideal choice for battery powered and portable applications.  
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 LM4120 is available in  
a standard 5-pin SOT-23 package.
