RS431-Q1/ RS432-Q1

RS431-Q1/ RS432-Q1 Precision Programmable Reference

1 FEATURES

3 DESCRIPTIONS

The RS431-Q1 and RS432-Q1 device are three-terminal

•

Qualified for Automotive Applications

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 32V 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.

AEC-Q100 Qualified with the Grade 1

Reference Voltage Tolerance at 25°C

0.5% (A Grade)

•

Programmable Output Voltage to 32 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-Q1 and RS432-Q1 devices are offered

in two grades, with initial tolerances (at 25°C) of 0.5%,

for A grade.
