DescriptionThe LM4120 deviceisa precision low-power, low
dropout bandgap voltage reference with upto 5-mA
output current source and sink capability.
This series reference operates with input voltagesas
low as2V and up to 12 V, consuming 160-µA
(typical) supply current.In power-down mode, device
current dropsto less than2 μA.
The LM4120 comesin two grades(A and Standard)
and seven voltage options for greater flexibility. The
best grade devices (A) have an initial accuracyof
0.2%, while the standard have an initial accuracyof
0.5%, both with a temperature coefficient of ppm/°C ensured from −40°Cto 125°C.
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.
The device performanceis ensured over the industrial
temperature range (−40°C to 85°C), while certain
specifications are ensured over the extended
temperature range (−40°Cto 125°C). ContactTI for
full specifications over the extended temperature
range. The LM4120is availableina standard 5-pin
SOT-23 package.
