TL431BIDBVRE4

Overview

The TL431BIDBVRE4 is a programmable shunt regulator manufactured by Texas Instruments. It operates as a precision voltage reference with an adjustable output range from 2.495 V to 36 V. The device features a typical initial accuracy of ±0.5% and supports a maximum cathode current of 100 mA. It is housed in a 5-pin SOT-23 package and is rated for operation within a temperature range of -40°C to +85°C.

Feature Summary

Provides precise adjustable voltage regulation via external resistor divider
Ensures high accuracy with tight initial tolerance specifications
Supports low standby current requirements for power efficiency

Applications

Precision voltage references in power supply circuits
Feedback control loops in switching regulators
Comparator applications requiring stable reference voltages

Procurement Notes

Verify the specific suffix E4 indicates lead-free composition and RoHS compliance status. Confirm the component is obsolete and no longer in production before finalizing design-in decisions. Ensure substitute components match the pinout and electrical characteristics of the original specification.

Selection Notes

Select this component when high accuracy is required in compact surface-mount designs. Consider the limited operating temperature range compared to extended variants. Evaluate alternative packages if higher thermal performance or different pin configurations are necessary for the target application.

Part Context

This part belongs to the TL431 family of adjustable shunt regulators, widely used in analog and mixed-signal electronics. The TL431 series serves as a versatile replacement for Zener diodes, offering superior stability and adjustability. It is a foundational component in Texas Instruments' power management portfolio.
