LT1029CZ#TRPBF

Voltage Reference Overview

The LT1029CZ#TRPBF is a precision 5V bandgap voltage reference IC manufactured by Analog Devices Inc. It operates in shunt or Zener mode, supporting both positive and negative reference configurations. The device features a fixed output voltage of 5V with ±1% initial accuracy and a temperature coefficient of 34 ppm/°C. It requires a cathode current of 700 µA for optimal performance and supports a maximum operating current of 10 mA. Packaged in a TO-92-3 through-hole case within a tape-and-reel format, it functions across a commercial temperature range of 0°C to 70°C.

Voltage Reference Feature Summary

• Capable of operation in either shunt or Zener modes for flexible circuit integration
• Supports dual polarity applications as a positive or negative reference source
• Provides stable 5V output with low temperature drift characteristics

Voltage Reference Applications

• LCD backlight measurement circuits
• Precision wideband current probe designs
• General-purpose positive or negative voltage reference generation

Voltage Reference Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to limited availability status. Confirm package integrity upon receipt, as the reel packaging requires specific handling procedures. Ensure design compatibility with the specified 700 µA cathode current requirement before finalizing procurement plans.

Voltage Reference Selection Notes

Select this component when a stable 5V reference is required in compact through-hole layouts. Consider the 34 ppm/°C temperature coefficient against application thermal stability needs. Verify that the 10 mA maximum current rating suffices for the intended load conditions without exceeding power dissipation limits in the TO-92-3 package.

Voltage Reference Part Context

This part belongs to the LT1029 series of 5V bandgap references from Analog Devices. It shares functional similarities with other shunt references but is distinct in its specific accuracy class and package configuration. The series is designed for applications requiring reliable voltage regulation without complex external compensation networks.

Voltage Reference Replacement Considerations

LT1029CZ#PBF serves as the tube-pack equivalent of this reel-part number. Substitution between these two variants maintains identical electrical specifications and pinout compatibility while differing only in manufacturing packaging format.
