LM4128
SOT-23 Precision Micropower Series Voltage Reference
General Description
Ideal for space critical applications, the LM4128 precision
voltage reference is available in the SOT-23 surface-mount
package. The LM4128’s advanced design eliminates the
need for an external stabilizing capacitor while ensuring sta-
bility with capacitive loads up to 10 μF, thus making the
LM4128 easy to use.
Series references provide lower power consumption than
shunt references, since they do not have to idle the maximum
possible load current under no load conditions. This advan-
tage, the low quiescent current (60 μA), and the low dropout
voltage (400 mV) make the LM4128 ideal for battery-powered
solutions.
The LM4128 is available in four grades (A, B, C, and D) for
greater flexibility. The best grade devices (A) have an initial
accuracy of 0.1% with guaranteed temperature coefficient of
75 ppm/°C or less, while the lowest grade parts (D) have an
initial accuracy of 1.0% and a tempco of 100 ppm/°C.
