Overview
The TLVH431IDCKR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 18 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of ±1.5% and supports a maximum cathode current of 70 mA with a minimum operating current of 100 µA. It is housed in a compact SC-70-6 surface-mount package and is rated for an operating temperature range of -40°C to +85°C.
Feature Summary
- Adjustable reference voltage capability spanning from 1.24 V to 18 V
- Compact SC-70-6 surface-mount package design for space-constrained applications
- Low minimum operating current requirement of 100 µA
Applications
- Portable battery-powered equipment requiring precise voltage regulation
- Power supply circuits utilizing adjustable shunt regulation
- General-purpose voltage reference implementations in consumer electronics
Procurement Notes
Verify the specific suffix 'IDCKR' against the manufacturer's official documentation to confirm the exact tolerance, package type, and tape-and-reel specifications. Ensure compatibility with the intended operating temperature range of -40°C to +85°C. Confirm RoHS compliance status through the latest datasheet revision before procurement.
Selection Notes
Select this component when a low-cost, adjustable shunt regulator is required in a small SC-70-6 footprint. It is suitable for applications needing ±1.5% accuracy and operation up to 18 V. Consider thermal performance and current limits relative to the specific circuit load requirements.
Part Context
This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators. The family includes variants with different accuracies and automotive qualifications. The IDCKR variant specifically denotes the standard commercial grade with ±1.5% initial accuracy in the SC-70-6 package.
Replacement Considerations
Direct replacements include other TLVH431 series parts with matching SC-70-6 packaging and similar electrical characteristics. Verify pinout compatibility and ensure the substitute meets the required 1.24 V to 18 V adjustment range and 70 mA current capability.
