LM385B-ADJ

Overview

The LM385B-ADJ is a two-terminal shunt voltage reference integrated circuit manufactured by TAEJIN Technology. It provides an adjustable output voltage ranging from 1.24 V to 5.3 V with an initial accuracy of ±1%. The device operates within a current range up to a maximum of 20 mA and is housed in a TO-92-3 package. It supports an operating temperature range of -40°C to +85°C, ensuring stable performance across industrial environments.

Feature Summary

• Adjustable output voltage capability spanning from 1.24 V to 5.3 V
• High initial accuracy specified at ±1%
• Two-terminal shunt regulation architecture for simplified circuit design

Applications

• Precision power management systems requiring stable reference voltages
• Test and measurement instrumentation calibration circuits
• Industrial control applications needing reliable voltage referencing

Procurement Notes

Verify the manufacturer designation as TAEJIN Technology when sourcing this component. Confirm the package type is TO-92-3 and the operating temperature range covers -40°C to +85°C. Ensure the specific suffix ADJ is present to guarantee adjustable functionality rather than fixed voltage variants. Cross-reference datasheets for exact electrical tolerances before integration.

Selection Notes

Select the LM385B-ADJ when an adjustable shunt reference is required within the 1.24 V to 5.3 V range. Consider its ±1% initial accuracy for applications demanding precise voltage levels without external trimming. The TO-92-3 package suits through-hole mounting requirements. Evaluate the 20 mA maximum current limit against load requirements to ensure proper operation within the specified thermal and electrical boundaries.

Part Context

This component belongs to the LM385 series of precision voltage references. While other variants like the LM385BM-1.2/NOPB offer fixed outputs in different packages such as SOIC-8, the LM385B-ADJ specifically provides adjustability. It serves as a fundamental building block for analog circuits where a stable, low-drift voltage source is critical for signal integrity and system accuracy.

Replacement Considerations

Direct substitutes may include other adjustable shunt references from manufacturers like Texas Instruments or HTC, provided they match the TO-92-3 package and voltage range. Verify pinout compatibility and thermal characteristics before substitution.
