LM285BXZ-1.2/T1

Overview

The LM285BXZ-1.2/T1 is a two-terminal shunt voltage reference IC manufactured by National Semiconductor. It provides a fixed output voltage of 1.235V with an initial accuracy of ±1%. The device supports a maximum output current of 20 mA and exhibits a temperature coefficient of 30ppm/°C. Noise performance is specified at 60μVrms within the 10Hz to 10kHz frequency range. It is housed in a TO-92-3 package suitable for through-hole mounting and operates within a temperature range of -40°C to +85°C.

Feature Summary

Fixed 1.235V shunt voltage reference output
Low noise performance for precision applications
Through-hole compatible TO-92-3 packaging

Applications

Precision measurement systems requiring stable reference voltages
Sensor signal conditioning circuits
Battery-powered instrumentation

Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets are managed by Texas Instruments. Confirm the specific suffix /T1 indicates tape-and-reel packaging if required for automated assembly. Ensure the component meets RoHS compliance standards for lead-free operation before integration into final products.

Selection Notes

Select this component when a low-cost, micropower shunt reference is needed for applications requiring 1.235V stability. Consider the 20mA current limit and TO-92 package constraints. Evaluate thermal management requirements given the through-hole mounting style and operating temperature range.

Part Context

This part belongs to the LM285 family of micropower voltage references. These devices utilize bandgap technology to provide stable reference voltages. The LM285 series is widely used in industrial and consumer electronics where cost-effective voltage regulation is critical.

Replacement Considerations

Check for direct equivalents such as the LM285BZ-1.2 or LM285AXZ-1.2 from National Semiconductor/TI. Verify pinout compatibility and electrical specifications before substituting.
