Overview
The LM385LPE3-2-5 is a micropower shunt voltage reference manufactured by Texas Instruments, providing a fixed nominal output of 2.5V. It operates within a temperature range of -40°C to +85°C and features an initial accuracy of 1.5%. The device utilizes a TO-92-3 through-hole package and supports a maximum shunt current of 20 mA with a minimum operating current of 20 µA. Its temperature coefficient is specified at 20 ppm/°C, ensuring stable performance across industrial environments.
Feature Summary
- Provides a precise 2.5V fixed reference voltage for circuit stability
- Operates efficiently with low quiescent current consumption
- Maintains high accuracy over extended industrial temperature ranges
Applications
- Portable battery-powered instrumentation requiring low power
- Industrial process control systems needing stable references
- Data acquisition systems utilizing analog-to-digital conversion
Procurement Notes
Verify the specific suffix 'E3' indicates lead-free compliance when sourcing. Confirm the TO-92-3 package availability matches your PCB layout requirements. Ensure the 1.5% initial accuracy meets your system tolerance specifications before finalizing procurement decisions.
Selection Notes
Select this component when a fixed 2.5V reference is required in a through-hole configuration. It is suitable for applications demanding better accuracy than standard zener diodes but lower cost than precision bandgap references. Consider the 20 ppm/°C temperature coefficient for thermal stability needs.
