SC431A, Programmable Precision References

DATA SHEET www.onsemi.com Programmable Precision References NCP431A, SC431A, NCP431B, SC431B, NCP432B, SC432B Series The NCP431/NCP432 integrated ci

Features

* Programmable Output Voltage to 36 V
* Low Minimum Operating Current: 40 mA, Typ @ 25°C
* Voltage Reference Tolerance: ±0.5%, Typ @ 25°C (NCP431B/NCP432B)
* Low Dynamic Output Impedance, 0.22 W Typical
* Sink Current Capability of 40 mA to 100 mA
* Eq

Applications

* such as digital voltmeters, power supplies, and op amp circuitry.
The 2.5 V reference makes it convenient to obtain a stable reference from 5.0 V logic supplies, and since the NCP431/ NCP432 operates as a shunt regulator, it can be used as either a positive or negative voltage reference.
