LM285Z-2.5G

Overview

The LM285Z-2.5G is a micropower two-terminal bandgap voltage reference diode manufactured by onsemi. It provides a nominal output voltage of 2.5 V with an initial accuracy of 1.5%. The device operates within a temperature range of -40 °C to +70 °C and features a maximum shunt current of 20 mA. Packaged in a TO-92 through-hole configuration, it is designed for applications requiring stable voltage regulation over time and temperature.

Feature Summary

Micropower two-terminal bandgap voltage regulator diode
Tight voltage tolerances achieved by on-chip trimming
Low dynamic impedance and low noise characteristics
Stable operation over extended time and temperature ranges

Applications

Portable instrumentation circuits
Battery-powered regulators
Micropower analog circuitry requiring extended battery life

Procurement Notes

Verify the manufacturer designation carefully, as the 'G' suffix typically indicates Green/RoHS-compliant packaging from onsemi. Confirm the package style matches the required TO-92 form factor. Ensure the operating temperature range aligns with the specified -40 °C to +70 °C limits for your specific application environment.

Selection Notes

Select this component when a fixed 2.5 V reference is needed in a through-hole package. It is suitable for designs prioritizing low power consumption and long-term stability. Consider the 1.5% initial accuracy and 20 mA maximum current limits during circuit design to ensure proper biasing and regulation performance.

Part Context

This part belongs to the LM285/LM385 series of micropower voltage reference diodes. These devices are engineered for wide dynamic current ranges, enabling use in applications with varying supply voltages. The series is characterized by exceptionally low dynamic impedance and noise, making it a standard choice for precision analog references in cost-sensitive designs.

Replacement Considerations

LM285Z-2.5/NOPB (Texas Instruments) offers similar electrical specifications but may differ in temperature range or tolerance details. Cross-reference datasheets for exact parameter alignment before substitution.
