TLV431BCPKG3

Overview

The TLV431BCPKG3 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 1.24 V to 6 V and features an initial accuracy of ±0.5%. The device supports a maximum cathode current of 15 mA and maintains a low temperature coefficient of 161 PPM/C. Designed for surface-mount applications, it utilizes the SOT-23-3 package. The component functions reliably across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Provides high-precision voltage regulation with tight initial accuracy tolerance
• Operates effectively at low supply voltages down to 1.24 V
• Features a compact three-terminal surface-mount package design

Applications

• Low-voltage power supply feedback loops
• Portable electronic equipment reference circuits
• Battery-powered system voltage monitoring

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm compliance with current environmental standards and material declarations. Ensure the selected package variant matches the intended PCB footprint requirements. Confirm availability status as product lifecycles may change without prior notice.

Selection Notes

Select this component when designing circuits requiring precise voltage referencing in space-constrained portable devices. The low minimum operating voltage makes it suitable for single-cell battery applications. Verify that the required cathode current does not exceed the 15 mA limit under all operating conditions.

Part Context

This part belongs to the TLV431 family of low-voltage adjustable shunt regulators. It serves as a modern alternative to standard TL431 devices in applications where lower input voltage operation is necessary. The family offers various accuracy grades and package options to suit different power management needs.
