SM74601 (ACTIVE)

SOT-23 Precision Micropower Series Voltage Reference



Ideal for space critical applications, the SM74601 precision voltage reference is available in the SOT-23 surface-mount package. The SM74601’s advanced design eliminates the need for an external stabilizing capacitor while ensuring stability with capacitive loads up to 10 µF, thus making the SM74601 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 advantage, the low quiescent current (60 µA), and the low dropout voltage (400 mV) make the SM74601 ideal for battery-powered solutions.
