LT1004CZ-1.2#PBF

Voltage Reference Overview

The LT1004CZ-1.2#PBF is a micropower voltage reference featuring a 2-terminal bandgap design in a 3-Lead Plastic TO-92 package. It provides a fixed output of 1.235V with guaranteed initial accuracy within ±4mV and an average temperature coefficient of 20ppm/°C. The device operates at a minimum current of 10µA and supports up to 20mA, maintaining very low dynamic impedance.

Voltage Reference Feature Summary

• Guaranteed high initial accuracy for the -1.2 variant
• Micropower operation optimized for low current consumption
• Excellent temperature stability characteristics
• Very low dynamic impedance performance

Voltage Reference Applications

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

Voltage Reference Procurement Notes

Verify that the specific suffix CZ corresponds to the commercial temperature range (0°C to 70°C) and the TO-92 package style required for your application. Confirm the -1.2 designation matches the necessary 1.235V output level. Ensure compliance with RoHS standards as indicated by the PBF suffix before finalizing procurement orders.

Voltage Reference Selection Notes

Select this component when system constraints demand minimal quiescent current alongside precise voltage regulation. The LT1004 serves as a pin-for-pin replacement for LM185/LM385 series references while offering superior accuracy specifications without requiring external trimming or higher power dissipation.
