LM4120  
SNVS049F FEBRUARY 2000REVISED MARCH 2016  
LM4120 Precision Micropower Low Dropout Voltage Reference  
1 Features  
3 Description  
The LM4120 device is a precision low-power, low  
dropout bandgap voltage reference with up to 5-mA  
output current source and sink capability.  
1
Small SOT23-5 Package  
Low Dropout Voltage: 120 mV Typical at 1 mA  
High Output Voltage Accuracy: 0.2%  
Source and Sink Current Output: ±5 mA  
Supply Current: 160 μA Typical  
Low Temperature Coefficient: 50 ppm/°C  
Enable Pin  
This series reference operates with input voltages as  
low as 2 V and up to 12 V, consuming 160-µA  
(typical) supply current. In power-down mode, device  
current drops to less than 2 μA.  
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 standard have an initial accuracy of  
0.5%, both with  
50 ppm/°C ensured from 40°C to 125°C.  
Fixed Output Voltages: 1.8, 2.048, 2.5, 3, 3.3,  
4.096, and 5 V  
Industrial Temperature Range: 40°C to 85°C  
a
temperature coefficient of  
(For Extended Temperature Range, 40°C to  
125°C, Contact TI)  
The very low dropout voltage, low supply current, and  
power-down capability of the LM4120 make this  
product an ideal choice for battery-powered and  
portable applications.  
2 Applications  
Portable, Battery-Powered Equipment  
Instrumentation and Process Control  
Automotive and Industrial  
Test Equipment  
The device performance is ensured over the industrial  
temperature range (40°C to 85°C), while certain  
specifications are ensured over the extended  
temperature range (40°C to 125°C). Contact TI for  
full specifications over the extended temperature  
range. The LM4120 is available in a standard 5-pin  
SOT-23 package.
