The Xinluda XB431-TL is a low-voltage, three-terminal adjustable precision shunt voltage reference belonging to the popular TL431-type family. Using two external resistors, its output voltage can be programmed to any value between the internal reference voltage (VREF = 1.24V) and 6V, making it a versatile, low-voltage alternative to traditional shunt references. Its active output stage delivers a fast turn-on characteristic and a low typical output impedance of 0.25Ω, which makes it especially well suited as the reference element in the isolated feedback loop of 3V to 3.3V switching power supplies when paired with an optocoupler.
The Xinluda XB431-TL is a specialty, low-availability part with little to no authorized-distributor stock, which can make it difficult to source through conventional channels. Pacific Component Xchange is an independent distributor focused on hard-to-find and obsolete power-management ICs, voltage references, and optocouplers. We help engineers and procurement teams secure the components that mainstream catalogs cannot supply.
Every XB431-TL we source is screened for authenticity and traceability, and we ship worldwide to keep your production lines and prototyping schedules on track. Because this is a Request-For-Quote (RFQ) item, pricing is provided on a per-order basis to reflect current market conditions and quantity. Submit an RFQ to Pacific Component Xchange today for current availability, lead time, and a competitive quote on the XB431-TL.
The XB431-TL is a low-voltage, three-terminal adjustable precision shunt voltage reference (TL431-type) from Xinluda. It has a 1.24V internal reference and an output that can be programmed from 1.24V to 6V using two external resistors, housed in a SOT-23-3 package.
The XB431-TL output voltage is adjustable from the internal reference voltage of 1.24V up to 6V, set by two external resistors.
The XB431-TL is supplied in a compact SOT-23-3 surface-mount package.
The XB431-TL has a typical output impedance of 0.25 Ohm and a typical cathode operating current of 80 uA, per the Xinluda datasheet.
The XB431-TL is a TL431-type adjustable shunt voltage reference. It is a low-voltage variant with a 1.24V reference and a 1.24V to 6V adjustable output, well suited for 3V to 3.3V isolated feedback loops. Confirm pin and parametric compatibility against your specific design before substituting.
The XB431-TL is a hard-to-find, Request-For-Quote item with limited authorized-distributor stock. Pacific Component Xchange specializes in sourcing scarce power-management and reference ICs. Submit an RFQ for current availability, lead time, and pricing.
