LT1431IZ#TRPBF

Voltage Reference Overview

The LT1431IZ#TRPBF is a programmable shunt voltage reference in a 3-lead TO-92 plastic package. It provides an adjustable output voltage range from 2.5V to 36V with a guaranteed initial voltage tolerance of 0.4%. The device features a typical dynamic output impedance of 0.1Ω and operates within a temperature range of -40°C to +85°C. It supports a sink current capability between 1mA and 100mA, with a minimum operating current of 0.6mA.

Voltage Reference Feature Summary

Guaranteed 0.4% initial voltage tolerance for high precision applications
Low reference pin input current with bias cancellation
Fast turn-on response time
Pin-compatible with TL431

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 when sourcing this component. Confirm that the 'I' grade designation matches the required industrial temperature range of -40°C to +85°C for your application environment. Ensure the 3-lead TO-92 package form factor fits the designated PCB footprint.

Voltage Reference Selection Notes

Select this part when a low-cost, pin-compatible alternative to the TL431 is required with tighter initial accuracy. The 0.4% tolerance offers better precision than standard shunt regulators. Consider the 3-lead configuration for simplified circuit layouts where external divider resistors are unnecessary for fixed 2.5V operation.

Voltage Reference Part Context

This component belongs to the LT1431 family of adjustable shunt voltage regulators manufactured by Analog Devices. The family includes various packages such as SOIC and DIP, but the IZ variant specifically utilizes the 3-lead TO-92 plastic housing. It serves as a foundational reference element in analog control loops and feedback networks.
