DESCRIPTION
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.
