Product details

Shunt reference that defined the adjustable standard

Its output is set with two external resistors anywhere between a 2.495 V minimum and a 36 V maximum, making it a flexible building block for linear supplies, isolated DC-DC converters, and supervisory circuits. Rated for a cathode current of 100 mA and a minimum of 700 µA to maintain regulation, this part suits designs that need a stable reference over a wide load range. The ±1% tolerance on the reference voltage keeps the feedback loop accurate without trimming.

Supplied in a surface-mount SOT-23-5 package (SC-74A, SOT-753 case code), this part is a compact fit for dense PCB layouts.
