Product details

Sourcing is limited to independent inventory — verified stock from franchised overruns, excess buybacks, and broker-held lots.

±1% reference accuracy — what it buys you

The ±1% tolerance on the internal reference voltage (2.495 V nominal) defines the output accuracy across the adjustable range up to 36 V. This is the standard precision grade for general-purpose power supply feedback, voltage monitoring, and comparator threshold circuits — tight enough for most non-critical regulation loops, but not the 0.5% or 0.1% grade needed for precision instrumentation or ADC references. Output current capability is 100 mA, which sets the load-driving boundary for the shunt regulator.

8-DIP through-hole — commercial temperature only

The 8-DIP (0.300-inch, 7.62 mm pitch) through-hole package suits breadboard prototyping, legacy PCB retrofits, and designs where wave soldering is preferred over reflow.
