LT1034IZ-2.5#PBF

Voltage Reference Overview

The LT1034IZ-2.5#PBF is a micropower voltage reference manufactured by Analog Devices (formerly Linear Technology). It provides a precise 2.5V output in a 3-pin TO-92 package. The device operates within a supply voltage range of 2.7V to 15V and delivers a maximum shunt current of 20mA. It features an initial accuracy of 1% and a temperature coefficient of 20ppm/°C, ensuring stable performance across commercial operating temperatures from 0°C to +70°C.

Voltage Reference Feature Summary

• Micropower bandgap architecture for low energy consumption
• High precision with 1% initial accuracy and 20ppm/°C temperature stability
• Integrated series regulation topology without requiring external compensation capacitors
• Reverse battery protection prevents damage during incorrect polarity connections

Voltage Reference Applications

• Precision analog-to-digital converter (ADC) reference sources
• Digital-to-analog converter (DAC) voltage references
• Battery-powered instrumentation systems
• Portable measurement equipment requiring stable voltage standards

Voltage Reference Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the manufacturer designation as Analog Devices Inc., noting the historical association with Linear Technology. Ensure the component matches the TO-92-3 physical package dimensions and pinout configuration required for your circuit design before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when a compact, low-power voltage reference is needed for commercial temperature applications. The 2.5V output level suits many microprocessor and data acquisition systems. Consider the 1% initial tolerance and 20ppm/°C drift characteristics against system requirements. The TO-92 package offers through-hole mounting options suitable for prototyping or specific mechanical constraints.

Voltage Reference Part Context

This part belongs to the LT1034 family of micropower dual references, though the LT1034IZ variant specifically provides a single 2.5V output. The family is known for combining bandgap core technology with trimmed precision thin-film resistors. This design allows the reference to operate efficiently over the entire load current range while maintaining high stability and low power consumption compared to standard zener references.
