XB385M3-1.2 – Voltage Reference – Xinluda

The Xinluda XB385M3-1.2 is a micropower 2-terminal shunt (bandgap) voltage reference with a 1.235 V output and 1% initial accuracy in a compact SOT-23-3 package. Available for RFQ from Pacific Component Xchange.

The Xinluda XB385M3-1.2 is a micropower 2-terminal shunt (bandgap) voltage reference that delivers a nominal 1.235 V reference voltage with 1% initial accuracy in a space-saving SOT-23-3 surface-mount package. It belongs to Xinluda’s 385-1.2 reference family and is a functional, pin-compatible equivalent to the industry-standard LM385-1.2 micropower voltage reference diode, making it a practical drop-in alternative for designs that need a low-power, low-cost shunt reference.

As a two-terminal shunt device, the XB385M3-1.2 operates much like a precision Zener: it is biased through a series resistor and maintains a stable reference voltage across its operating current range while drawing low quiescent current. This makes it well suited to battery-powered and portable equipment where micropower operation and a small footprint are important.

Note: Specifications listed above are those published on the Xinluda 385-1.2 series documentation. Detailed electrical limits (operating current range, dynamic impedance, temperature coefficient and operating temperature range) follow the LM385-1.2 reference class; consult the manufacturer datasheet to confirm exact limits for your design before committing to production.

Applications

• Portable and battery-powered instrumentation
• Low-power ADC / DAC reference and bias networks
• Threshold and comparator reference voltages
• Sensor signal-conditioning circuits
• Handheld meters and data-logging equipment
