Voltage References

Offered in a choice of space-saving packages, Diodes Incorporated Voltage References provide the opportunity to reduce power consumption and increase operating temperature. 

Diodes' shunt references offer the industry standard LM4040 types as well as several options for more demanding applications. Reference voltages from 1.22V to 5V are available with tolerance down to 0.5%.

Our shunt voltage regulator portfolio includes 2.5V, 1.24V, and 0.6V reference voltage devices covering consumer, computing, industrial, and automotive applications. It includes industry standard TL431 and TL432 equivalents, as well as footprint compatible, very low minimum (knee) current for latest low standby power isolated power supplies. Additionally, it includes a well enhanced operating voltage range TLV431 (1.24V) equivalents. All of the 2.5V and 1.24V support operating temperatures up to 125°C as standard, therefore reducing the number of variants that need to be qualified and stocked. Automotive-compliant variants are available which are qualified to AEC-Q100 Grade 1 in IATF 16949 facilities supporting PPAP documentation.
