Ideal for space-critical applications, the LM4128's high-precision voltage-referenced SOT-23 surface-mount package. The LM4128's advanced design eliminates the need for external stabilized capacitors while ensuring capacitive load stability up to 10μF, making it easy to use with the LM4128.

Series voltage references provide lower power consumption than parallel references because they do not have the maximum possible load current under idle no-load conditions. The advantages of this are low quiescent current (60μA), low dropout (400 mV) to make the LM4128 battery-powered ideal for solutions.

The LM4128 is available in four grades (A, B, and D) for greater flexibility. The best grade device (1) has an initial accuracy of 0.1% and guarantees a temperature coefficient of 75 PPM/°C or less, while the lowest grade (IV) has an initial accuracy of 1.0% and a temperature coefficient of 100 PPM/°C.
