Overview
The TLV431BCDBVTE4 is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an input voltage range of 2.5 V to 36 V and provides an adjustable output voltage from 2.495 V to 36 V. The device features an initial accuracy of ±0.5% and supports a maximum cathode current of 100 mA. It is housed in a surface-mount SOT-23-5 package (SC-74A) and is rated for operation between 0°C and 70°C.
Feature Summary
- Adjustable reference voltage capability across a wide operating range
- High DC voltage gain for precise regulation performance
- Low dynamic impedance ensuring stable output under varying load conditions
Applications
- Precision voltage references in power supply circuits
- Comparator applications requiring high gain
- Linear regulators and post-regulation stages
Procurement Notes
Verify the specific suffix 'E4' confirms lead-free and RoHS compliance status as per manufacturer documentation. Confirm the SOT-23-5 package marking and pinout alignment with design schematics. Ensure the 0°C to 70°C industrial temperature range meets system environmental requirements before integration.
Selection Notes
Select this component when a 36 V input range and 100 mA sink current are required. The ±0.5% accuracy suits applications needing tighter tolerance than standard TLV431 variants. Compare against TLV431BIDBVTG4 if automotive qualification or extended temperature ranges are necessary, as this part is limited to industrial temperatures.
Part Context
This device belongs to the TLV431 family of adjustable shunt regulators, designed as a drop-in replacement for the legacy TL431. It offers improved low-voltage performance compared to traditional Zener-based references while maintaining compatibility with standard feedback loop configurations in switching and linear power supplies.
Replacement Considerations
Direct substitutes include TLV431BCDBVT and TLV431BCDBVTE4 equivalents from other manufacturers such as Diodes Incorporated or STMicroelectronics, provided pinouts and electrical specifications match.
