Overview
The LM285Z-2.5RPG is a micropower shunt voltage reference diode manufactured by onsemi, featuring a fixed output voltage of 2.5 V with an initial accuracy of ±1.5%. It operates within a temperature range of -40°C to +85°C and supports a maximum shunt current of 20 mA. The device utilizes a TO-92-3 through-hole package and exhibits a typical temperature coefficient of 80 ppm/°C.
Feature Summary
- Provides stable 2.5 V reference via two-terminal shunt topology
- Designed for low-power applications with micropower operation
- Maintains performance across industrial temperature ranges
Applications
- Portable instrumentation circuits
- Analog-to-digital converter (ADC) references
- Digital-to-analog converter (DAC) biasing
Procurement Notes
Verify the specific suffix 'RPG' against official onsemi documentation to confirm tape-and-reel packaging specifications. Ensure the component matches the required lead-free status and RoHS compliance standards for your assembly process. Cross-reference the datasheet revision date to validate parameter consistency before integration.
Selection Notes
Select this component when a fixed 2.5 V precision reference is required in a through-hole TO-92 form factor. It is suitable for designs prioritizing low quiescent current and moderate accuracy over wide temperature variations. Compare against LM285Z-2.5 variants if surface-mount or different tolerance grades are needed.
Part Context
This part belongs to the LM285 series of micropower voltage references, which includes adjustable and fixed versions. The LM285 family is widely used in battery-powered systems due to its low current consumption. The Z-series typically denotes the TO-92 package variant, while the RPG suffix indicates specific reel packaging from onsemi.
Replacement Considerations
LM285Z-2.5/NOPB (Texas Instruments): Pin-compatible alternative with similar electrical characteristics. LM285Z-2.5G (onsemi): Same manufacturer, bulk packaging variant. Verify temperature coefficient and dynamic impedance differences before substitution.
