LM385Z-1.2RAG

Overview

The LM385Z-1.2RAG is a micropower shunt voltage reference diode manufactured by onsemi, featuring a nominal output of 1.235V in a TO-92 package. It operates within a wide current range of 10µA to 20mA with an initial accuracy of ±2%. The device exhibits low dynamic impedance and low noise, ensuring stable performance across temperatures from 0°C to +70°C.

Feature Summary

Micropower design suitable for battery-operated applications
Low dynamic impedance for improved regulation
Wide operating current range from 10µA to 20mA

Applications

Portable instrumentation
Battery-powered circuits
Analog reference sources

Procurement Notes

Verify component authenticity through authorized channels as the manufacturer has indicated obsolescence status. Confirm specific lot codes and RoHS compliance documentation prior to integration. Ensure supply chain stability due to potential discontinuation risks associated with this part number.

Selection Notes

Select this component for designs requiring a precise 1.235V reference in space-constrained TO-92 packages. Consider the ±2% tolerance and temperature coefficient when designing high-precision analog front ends. Evaluate power consumption constraints against the 10µA minimum operating current requirement.

Part Context

This device belongs to the LM385 series of micropower voltage references. It serves as a fixed shunt regulator alternative to Zener diodes, offering superior temperature stability and lower noise characteristics. The series is widely used in precision measurement and control systems.
