RS431/ RS432 Precision Programmable Reference

1 FEATURES

3 DESCRIPTIONS

The RS431 and RS432 device are three-terminal

•

Reference Voltage Tolerance at 25°C

adjustable shunt regulators, with a guaranteed thermal

stability over applicable temperature ranges. The output

voltage can be set to any value between V_REF

(approximately 2.5V) and 36V with two external

resistors. These devices have provided a very sharp

turn-on characteristic, making these devices excellent

replacement for Zener diodes in many applications.

0.5% (A Grade)

1% (B Grade)

•

Programmable Output Voltage to 36 V

Low Dynamic Output Impedance 0.2 Ω

Sink Current Capability of 0.5mA to 100mA

Equivalent Full-Range Temperature

Coefficient of 50ppm/°C Typical

Temperature Compensated for Operation

Over Full Rated Operating Temperature

Range

•

Both the RS431 and RS432 devices are offered in two

grades, with initial tolerances (at 25°C) of 0.5% and 1%,

for A and B grade.
