Product details

Precision adjustable shunt reference in SOT-23-3

The SOT-23-3 package and 65 µA cathode current suit it for battery-powered or energy-harvesting designs that cannot spare a dedicated reference rail.

Noise and output range

The output can be set anywhere between the 1.212 V minimum and the 10 V maximum, limited only by the cathode current and the external resistor divider. Maximum output current is 12 mA, so the reference can also bias a small load or provide a virtual ground.

The base product number LM4051 covers multiple tolerance and package variants, but this specific -ADJ/NOPB trim is the adjustable output in the SOT-23-3 package.
