JVR431

Shunt Voltage Reference

Description

Features and Benefits

The JVR431 is a high-precision shunt voltage reference with

outstanding thermal stability over the operating temperature between

-40ºC and 125ºC.

•

Programmable output voltage (2.5 ~ 36V) with tolerance at 0.4%

Low drift (4.5mV typical) upon V_REFover full operating temp. range

Very low drift (20 ppm/C typical) upon reference voltage (V_REF

over wide operating temperature range (-40C ~ 125ºC)

Small dynamic output resistance at 0.15Ω typical

Ability to sink current from 1mA ~ 100mA

)

The JVR431 is designed to turn ON rapidly and exhibits low output

impedance and temperature coefficient. As such, the device

responds promptly to changes in the load condition while a steady

V_REFoutput is maintained. In CE / industrial / automotive applications,

JVR431 is an ideal replacement for Zener diode in ADCs / DACs

circuits to extend ENOB (effective number of bits), in AC-DC & DC-

DC circuits to provide voltage reference.

•

Stable operation with capacitive load at the output

Lead-free package assembled with ‘green’ molding compound

Packages offered include SOT-23.
