LT1431CS8#TRPBF

Voltage Reference Overview

The LT1431CS8#TRPBF is an adjustable shunt voltage regulator in an 8-lead plastic SO package. It provides a guaranteed 0.4% initial reference voltage tolerance and operates within a 0°C to 70°C temperature range. The device supports cathode voltages from 2.5V to 36V with a typical quiescent current of 0.6mA. It features a 100mA sink capability, a dynamic output impedance of 0.1Ω, and a reference drift of 30ppm/°C.

Voltage Reference Feature Summary

• Guaranteed 0.4% initial voltage tolerance
• Fast turn-on response
• Low reference pin input current
• Sink current capability ranging from 1mA to 100mA

Voltage Reference Applications

• Linear regulators
• Adjustable power supplies
• Switching power supplies

Voltage Reference Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging for surface mount assembly. Confirm the CS8 designation corresponds to the 8-lead plastic small outline package. Ensure the component grade meets the required 0°C to 70°C operating temperature specifications for the target application environment.

Voltage Reference Selection Notes

Select this part when precise initial voltage accuracy is critical. The 8-pin configuration allows for external compensation via the COMP pin and flexible feedback network design using RTOP and RMID pins. Consider thermal dissipation requirements given the junction temperature limits associated with the SO-8 package.

Voltage Reference Part Context

This component belongs to the LT1431 family of programmable references. It serves as a high-precision alternative to standard shunt regulators, offering superior initial tolerance and stability. The device integrates internal divider resistors for simplified 5V regulation configurations without external components.
