The XB431-LM is a three-terminal adjustable precision shunt voltage reference manufactured by Xinluda Information Technology Co., Ltd. Functionally compatible with the industry-standard TL431 family, the device provides a stable 1.24 V bandgap reference that can be programmed to any cathode voltage between 1.24 V and 30 V using two external resistors. Internal negative feedback from the cathode to the ADJUST (reference) pin holds the programmed output, much like a non-inverting amplifier, making the XB431-LM a versatile building block for regulation, monitoring, and error-amplifier circuits.
With a tight 1.0% initial tolerance, low 55 µA operating current, and a low 0.25 Ω dynamic output impedance, the XB431-LM is well suited to space-constrained power and feedback designs. The SOT-23-3 surface-mount package and -40 °C to +85 °C operating range make it a practical drop-in shunt reference for consumer, industrial, and embedded power supplies.
The XB431-LM is a hard-to-find part with limited authorized-distributor coverage in Western markets. Pacific Component Xchange is an independent distributor specializing in scarce power-management ICs and voltage references like the XB431-LM. We help engineers and buyers secure obsolete, allocated, and low-availability components through verified global supply channels.
Every order is backed by our authenticity and quality assurance program, with inspection and traceability to protect your build against counterfeit risk. We ship worldwide and can support both prototype quantities and production volumes. Because this is a Request-for-Quote item, pricing and lead time are confirmed per order. Submit an RFQ to Pacific Component Xchange today for current availability and a competitive quote on the XB431-LM.
The XB431-LM is an adjustable precision shunt voltage reference from Xinluda. It uses a 1.24 V internal bandgap reference and can be programmed to any cathode voltage between 1.24 V and 30 V with two external resistors, similar to the industry-standard TL431.
The XB431-LM is supplied in a compact SOT-23-3 surface-mount package. Confirm tape-and-reel quantity and packaging details with Pacific Component Xchange when you request a quote.
The internal bandgap reference is 1.24 V with a 1.0% initial tolerance. The programmable cathode (output) voltage ranges from 1.24 V up to 30 V.
Yes. The XB431-LM uses a TL431-type adjustable shunt regulator architecture with cathode-to-reference negative feedback, making it functionally suitable for many TL431-style reference, regulator, and error-amplifier applications. Always confirm pinout and electrical limits against the datasheet for your design.
The XB431-LM operates over a -40 u00b0C to +85 u00b0C temperature range, suitable for consumer, industrial, and embedded power applications.
Pacific Component Xchange is an independent distributor that sources scarce and low-availability parts like the XB431-LM. Submit a Request for Quote (RFQ) and our team will confirm current availability, lead time, and pricing with authenticity assurance and worldwide shipping.
