LM4125
Precision Micropower Low Dropout Voltage Reference
General Description
The LM4125 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 6V consuming 160 μA (Typ.) supply current. In
power down mode, device current drops to less than 2 μA.
The LM4125 comes in two grades (A and Standard) and
three 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 40C to +125C.
The very low dropout voltage, low supply current and power-
down capability of the LM4125 makes this product an ideal
choice for battery powered and portable applications.
The device performance is guaranteed over the industrial
temperature range (40C to +85C), while certain specs are
guaranteed over the extended temperature range (40C to
+125C). Please contact National for full specifications over
the extended temperature range. The LM4125 is available in
a standard 5-pin SOT-23 package.
