LT1460HCS3-3.3#TRPBF

Voltage Reference Overview

The LT1460HCS3-3.3#TRPBF is a micropower bandgap series voltage reference manufactured by Analog Devices Inc., housed in a 3-lead plastic SOT-23 package. It provides a fixed output voltage of 3.3V with an initial accuracy of ±0.40% and a maximum temperature coefficient of 20ppm/°C over the commercial operating range of 0°C to 70°C. The device features low supply current, typically 180µA, and can source up to 20mA of load current. It operates with a minimum input-output differential of 0.9V and includes reverse battery protection.

Voltage Reference Feature Summary

• Utilizes curvature compensation and trimmed precision thin-film resistors for high accuracy and low drift
• Capable of sourcing up to 20mA while maintaining excellent line regulation characteristics
• Operates stably with capacitive loads without requiring an external output compensation capacitor
• 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 ordering suffix #TRMPBF or #TRPBF against the required packaging format (Tape and Reel Mini vs Tape and Reel) as these denote different shipping quantities. Confirm the temperature grade 'C' corresponds to the intended commercial application range. Ensure the component matches the manufacturer's lead-free finish specifications and RoHS compliance requirements for the target assembly process.

Voltage Reference Selection Notes

Select this part when a compact SOT-23 footprint is required alongside precise voltage referencing capabilities. Consider the 20ppm/°C temperature coefficient limit if the operating environment exceeds standard commercial temperatures. Evaluate the 180µA typical supply current against system power budgets, noting that lower quiescent consumption is available in other variants within the LT1460 family.

Voltage Reference Part Context

This component belongs to the LT1460 Micropower Precision Series Reference Family, which offers various output voltages and packages including MSOP, SO, PDIP, TO-92, and SOT-23. The HCS3 designation specifically identifies the 3.3V output version packaged in the small 3-lead SOT-23 form factor, designed for space-constrained applications requiring stable reference voltages.
