illustrate
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 stabilizing capacitors while ensuring capacitive load stabilization up to 10μF, making the LM4128 easy to use.
Series voltage references provide lower power dissipation 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 (60 μA), low dropout (400 mV) to make the LM4128 battery-powered solution ideal.
The LM4128 is available in four grades (A, B, and D) for greater flexibility. THE BEST GRADE DEVICE (I) HAS AN INITIAL ACCURACY OF 0.1% AND GUARANTEES A TEMPERATURE COEFFICIENT OF 75 PPM/° C OR LESS, WHILE THE LOWEST STAGE PART (IV) HAS AN INITIAL ACCURACY OF 1.0% AND A TEMPERATURE COEFFICIENT OF 100 PPM/° C.
