LM285BYZ/NOPB

Overview

The LM285BYZ/NOPB is an adjustable micropower voltage reference from Texas Instruments, housed in a TO-92-3 through-hole package. It operates within a temperature range of -40°C to +85°C and supports an output voltage range of 1.24 V to 5.3 V. The device features an initial accuracy of 2% and a temperature coefficient of 150 ppm/°C. Maximum shunt current is rated at 20 mA, with a minimum operating current of 10 µA.

Feature Summary

• Provides stable voltage referencing via shunt regulation architecture
• Enables precise voltage setting across a wide adjustable range
• Operates efficiently with low quiescent current consumption

Applications

• Battery-powered instrumentation requiring low power consumption
• Portable measurement devices needing stable reference voltages
• Temperature-compensated oscillator circuits

Procurement Notes

Verify the specific suffix 'BYZ' against official Texas Instruments documentation to confirm the exact electrical characteristics and pinout configuration for your design requirements. Ensure compatibility with existing PCB footprints and thermal management strategies before finalizing procurement decisions.

Selection Notes

Select this component when an adjustable reference is required in a compact TO-92 package. It is suitable for applications demanding moderate accuracy (2%) and operation over standard industrial temperature ranges. Consider the 150 ppm/°C drift if high precision stability is critical for the system performance.

Part Context

This part belongs to the LM285 family of micropower voltage references. It shares functional similarities with other variants like the LM285Z-2.5/NOPB but offers adjustable output capabilities rather than fixed voltage options. The NOPB suffix indicates lead-free construction compliant with RoHS standards.

Replacement Considerations

LM285BXZ/NOPB is a confirmed substitute offering identical adjustable functionality and specifications within the same package type.
