LT1460GCZ-2.5#PBF

Voltage Reference Overview

The LT1460GCZ-2.5#PBF is a micropower precision series voltage reference manufactured by Analog Devices Inc., housed in a 3-lead TO-92 plastic package. It provides a nominal output voltage of 2.5V with an initial accuracy tolerance of ±0.25%. The device operates within a commercial temperature range of 0°C to 70°C and features a maximum temperature coefficient of 25ppm/°C. It supports a minimum output sourcing current of 20mA and maintains a low supply current of approximately 130µA for the 2.5V variant.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed thin-film resistors to achieve high output accuracy and low drift.
• Capable of supplying up to 20mA of load current while maintaining excellent line regulation characteristics.
• Operates stably with capacitive loads without requiring external output compensation capacitors.
• Includes reverse battery protection that prevents current conduction during reverse connections.

Voltage Reference Applications

• Handheld Instruments
• Precision Regulators
• A/D and D/A Converters
• Power Supplies
• Hard Disk Drives

Voltage Reference Procurement Notes

Verify the specific suffix GCZ corresponds to the 3-lead TO-92 package and commercial temperature grade (0°C to 70°C). Confirm the #PBF designation indicates lead-free finish compliance. Ensure the -2.5 suffix matches the required 2.5V output voltage specification for the target circuit design.

Voltage Reference Selection Notes

Select this component when a through-hole TO-92 package is preferred over surface-mount options like SO-8 or MSOP. Choose this part if the application requires a 2.5V reference with ±0.25% initial accuracy and can tolerate a 25ppm/°C temperature coefficient within the commercial temperature range.
