Overview
The LM385Z-2.5/NOPB is a micropower shunt voltage reference from Texas Instruments, providing a fixed output of 2.5 V. It features an initial accuracy of 3% and a temperature coefficient of 150 ppm/°C. The device operates within a junction current range of 20 µA to 20 mA and supports a maximum power dissipation of 400 mW. It is housed in a TO-92-3 through-hole package and functions across a commercial temperature range of 0°C to +70°C.
Feature Summary
- Provides a stable 2.5 V reference voltage using zener breakdown principles
- Designed for low-power applications with microampere operating currents
- Offers reliable performance across standard commercial temperature ranges
Applications
- Portable battery-powered instrumentation
- Data acquisition systems requiring stable reference voltages
- Microprocessor reset circuits and threshold detectors
Procurement Notes
Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance as per manufacturer specifications. Ensure the ordering part number matches the exact tolerance and package requirements for your design. Confirm that the commercial temperature range (0°C to +70°C) meets your operational environment needs before finalizing procurement.
Selection Notes
Select this component when a fixed 2.5 V reference is required in a cost-effective through-hole package. It is suitable for designs where moderate accuracy (3%) and a 150 ppm/°C temperature coefficient are acceptable. Consider alternative packages or tighter tolerances if higher precision or surface-mount integration is necessary for the application.
Part Context
This part belongs to the LM385 family of adjustable and fixed micropower voltage references. The 'Z' designation indicates a TO-92-3 through-hole package, while '-2.5' specifies the fixed 2.5 V output voltage. The '/NOPB' suffix denotes a non-plastic-bodied, lead-free, and RoHS-compliant version manufactured by Texas Instruments.
Replacement Considerations
LM385Z-2.5: Previous generation version without RoHS compliance. LM285Z-2.5/NOPB: Similar device with slightly different initial accuracy specifications.
