TL431CDBVTG4

Overview

The TL431CDBVTG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495 V to 36 V and provides an initial accuracy of ±2%. The device supports a maximum cathode current of 100 mA and features a temperature coefficient of 92 ppm/°C. Designed for surface-mount applications, it utilizes a 5-pin SOT-23 package (SC-74A). The component functions reliably across an operating temperature range from 0°C to +70°C.

Feature Summary

Provides stable reference voltage through adjustable shunt regulation topology
Ensures high precision with low initial output voltage tolerance
Supports wide input voltage operation suitable for various power supply architectures

Applications

Portable equipment power supplies
DC-to-DC converters
Internal voltage references
Post-regulators

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the package designation matches the required SC-74A or SOT-23-5 footprint for PCB layout compatibility. Ensure the operating temperature range meets the environmental requirements of the target application before finalizing procurement.

Selection Notes

Select this component when a compact, low-cost adjustable reference is needed for standard commercial temperature ranges. Compare against TLV431 variants if lower voltage operation or improved accuracy is required. Verify that the 100 mA cathode current capability aligns with the load requirements of the specific circuit design.

Part Context

This part belongs to the TL431 family of adjustable precision shunt regulators. It serves as a direct replacement for legacy TL431 devices in many designs while offering modern packaging and compliance standards. The family is widely used in power management circuits requiring stable voltage references.
