LT1004CZ-2.5#TRPBF

Voltage Reference Overview

The LT1004CZ-2.5#TRPBF is a micropower voltage reference featuring a two-terminal bandgap design in a 3-Lead Plastic TO-92 package. It provides a fixed output of 2.5V with guaranteed ±20mV initial accuracy and operates at currents up to 20mA. The device maintains a typical temperature coefficient of 20ppm/°C across the commercial range of 0°C to 70°C, ensuring stable performance for precision applications requiring low power consumption.

Voltage Reference Feature Summary

• Two-terminal bandgap reference diode architecture
• Guaranteed ±20mV initial accuracy for the 2.5V variant
• Micropower operation down to 10µA quiescent current
• Very low dynamic impedance for high stability

Voltage Reference Applications

• Portable meter references
• Battery-operated systems
• Current loop instrumentation
• Micropower cold junction compensation for thermocouples

Voltage Reference Procurement Notes

Verify that the specific suffix #TRPBF corresponds to the Tape and Reel packaging format as indicated in the ordering information table. Confirm the component falls within the commercial temperature range (0°C to 70°C) required for your application environment. Ensure the input reverse current does not exceed the absolute maximum ratings during operation.

Voltage Reference Selection Notes

Select this part when a low-cost, two-terminal shunt reference is sufficient compared to three-terminal series regulators. It serves as a pin-for-pin replacement for LM185/LM385 series references but offers improved accuracy specifications. Consider the TO-92 package constraints if thermal dissipation or board space are limiting factors in the design.
