Fixed 3.3 V rail for precision bias and ADC references
The REF196GRUZ-REEL7 is a fixed 3.3 V output series voltage reference from the REF19 family, trimmed to ±0.3% initial tolerance and a 25 ppm/°C temperature coefficient. It operates from a 3.5 V to 15 V input and delivers up to 30 mA to the load, with a quiescent supply current of only 45 µA. The 8-TSSOP package (4.40 mm width) fits surface-mount layouts where board area is tight. Typical applications include precision ADC and DAC reference biasing, regulator tracking, and portable instrumentation where the combination of low dropout and low quiescent current matters.
What the ratings mean for the BOM
The 30 mA output current biases multiple ADC reference inputs without an external buffer. The 45 µA supply current keeps the power budget tight in battery-powered designs. The -40°C to 85°C operating range covers industrial environments.
Lifecycle and sourcing reality
The REF196GRUZ-REEL7 carries an Active lifecycle status and is ROHS3 compliant. No end-of-life notice or last-time-buy schedule is in effect, so new designs can commit this part without near-term obsolescence risk.
