It delivers a stable 2.5V output with a ±1.5% tolerance and a typical temperature coefficient of 20 ppm/°C, making it a straightforward choice for biasing ADCs, setting comparator thresholds, or providing a precision rail in low-power analog circuits. The shunt topology means it behaves like a two-terminal Zener — you bias it with a resistor from the supply, and it sinks enough cathode current (minimum 20 µA) to regulate. Output current is rated at 20 mA, so it can drive a small load or feed the reference input of a converter directly.
Package and mounting — through-hole, rework-friendly
Housed in a TO-92-3 (TO-226AA) through-hole package, this reference is a direct fit for legacy board layouts and prototype builds. The three leads are on 0.1-inch pitch, easy to hand-solder or socket. No special thermal management needed at the 20 mA output level — the junction stays cool in still air at 25°C ambient.
