XT385-1.2 – Voltage Reference – Xinluda

The XT385-1.2 from Xinluda is a micropower 1.235V two-terminal shunt (parallel) bandgap voltage reference diode in a TO-92-3 package, designed for low-power precision biasing applications. Available for RFQ at Pacific Component Xchange.

The XT385-1.2 is a micropower 2-terminal band-gap voltage reference diode manufactured by Xinluda (Shenzhen Xinluda Information Technology Co., Ltd.). It provides a fixed 1.235V reference with ±1% initial tolerance and operates as a two-terminal shunt (parallel) device much like a precision zener, making it a functional equivalent of the popular LM385-1.2 family. Operating over a 10µA to 20mA current range, it features exceptionally low dynamic impedance and good temperature stability, making it ideal for battery-powered and portable designs where minimizing quiescent draw is critical.

Housed in a through-hole TO-92-3 package, the XT385-1.2 delivers stable, low-noise reference performance, supporting analog circuits that demand a dependable voltage anchor without the power overhead of series references. On-chip trimming is used to provide tight voltage tolerance.

Key Features

• Fixed reference (reverse breakdown) voltage: 1.235V (typical)
