LM285BXZ/NOPB

Overview

The LM285BXZ/NOPB is a micropower shunt adjustable voltage reference manufactured by Texas Instruments. It operates within a -40°C to +85°C temperature range and utilizes a TO-92-3 through-hole package. The device provides an adjustable output voltage ranging from 1.24 V to 5.3 V with an initial accuracy of 2%. It features a temperature coefficient of 150 ppm/°C and supports a maximum shunt current of 20 mA.

Feature Summary

Adjustable output voltage capability spanning 1.24 V to 5.3 V
Micropower operation suitable for low-energy applications
Shunt regulation topology for stable reference generation

Applications

Portable instrumentation circuits requiring precise voltage references
Battery-powered systems needing efficient power management
General-purpose analog signal conditioning stages

Procurement Notes

Verify the specific suffix configuration against the manufacturer's latest datasheet to ensure compatibility with required tolerance and packaging specifications. Confirm that the TO-92-3 through-hole form factor aligns with the target PCB layout constraints. Cross-reference the 2% initial accuracy and 150 ppm/°C temperature coefficient requirements with the design specifications before finalizing procurement orders.

Selection Notes

Select this component when an adjustable shunt reference is required in a through-hole package. The 1.24 V to 5.3 V adjustment range offers flexibility for various reference levels. Ensure the circuit design accommodates the 20 mA maximum shunt current limit. The 2% initial accuracy is sufficient for general applications, while the 150 ppm/°C coefficient defines thermal stability performance.

Part Context

This part belongs to the LM285 series of micropower voltage references. It serves as an adjustable variant within the family, distinct from fixed-voltage versions like the LM285Z-2.5. The series is designed for cost-sensitive applications requiring reliable voltage referencing in compact packages.
