LM385D-2.5

Overview

The LM385D-2.5G is a precision shunt voltage reference from onsemi, providing a fixed 2.5V output with ±3% initial accuracy. It operates in surface-mount SOIC-8 packages and supports a maximum output current of 20mA. The device features an 80 ppm/°C temperature coefficient and maintains stable regulation across a commercial operating temperature range of 0°C to 70°C.

Feature Summary

Fixed 2.5V precision reference voltage
±3% initial accuracy specification
Shunt regulator topology design
Surface-mount SOIC-8 package configuration

Applications

Precision analog circuit references
Data acquisition systems

Microprocessor supply monitoring circuits

Procurement Notes

Verify the specific suffix 'G' for lead-free compliance when ordering. Confirm that the SOIC-8 package variant matches the required PCB footprint dimensions. Ensure the selected component meets the 0°C to 70°C commercial temperature requirements for the intended application environment.

Selection Notes

Select this part for applications requiring a stable 2.5V reference with moderate accuracy. Consider the 80 ppm/°C temperature drift if operating outside standard room conditions. Verify that the 20mA maximum current capability aligns with the load requirements of the target circuit design.

Part Context

This component belongs to the LM385 series of micro-power two-terminal bandgap voltage references. It serves as a cost-effective alternative to more complex three-terminal regulators, offering high stability and low dynamic impedance suitable for general-purpose precision applications.
