LM285Z-1.2/NOPB

Overview

The LM285Z-1.2/NOPB is a micropower shunt voltage reference manufactured by Texas Instruments, designed for precision applications requiring stable voltage regulation. It operates within a temperature range of -40°C to +85°C and utilizes a TO-92-3 through-hole package. The device provides a fixed output voltage of 1.235 V with an initial accuracy of ±1%. It supports a maximum shunt current of 20 mA and features a temperature coefficient of 150 ppm/°C, ensuring reliable performance in portable instruments and sensor interfaces.

Feature Summary

Provides a fixed 1.235 V reference voltage suitable for precision analog circuits
Operates over a wide industrial temperature range from -40°C to +85°C
Features low dynamic impedance and low noise characteristics for signal integrity
Designed for micropower applications with operation down to 10 µA

Applications

Portable battery-powered instrumentation
Sensor interface circuits requiring stable biasing
Data acquisition systems with ADC/DAC references
Linear regulator feedback networks

Procurement Notes

Verify the specific suffix /NOPB confirms lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the TO-92-3 package orientation and pinout match the target PCB footprint. Ensure the 1.235 V fixed output aligns with circuit requirements, distinguishing it from adjustable variants like the LM285Z-NOPB. Check for any recent PCN updates regarding material or assembly changes.

Selection Notes

Select this component when a fixed 1.235 V reference is required in a through-hole TO-92 package. It is appropriate for designs prioritizing low power consumption and moderate precision (±1%). Compare against higher accuracy grades if tighter tolerances are needed. Consider the 150 ppm/°C temperature coefficient for thermal stability requirements in the operating environment.

Part Context

This part belongs to the LM285 series of micropower shunt voltage references from Texas Instruments. It shares architectural similarities with the LM385 family but offers specific performance optimizations for low-power applications. The /NOPB suffix indicates a non-plated lead-free version compliant with environmental directives, replacing older tin-lead variants in the product line.
