Overview
The TLVH431IDBVR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.5 V to 20 V and provides an adjustable output voltage from 1.24 V to 18 V. The device features an initial accuracy of ±1.5% and a temperature coefficient of 138 ppm/°C. It supports a maximum cathode current of 80 mA with a minimum operating current of 100 µA. The component functions across a temperature range of -40°C to +85°C and is housed in a SOT-23-5 surface-mount package.
Feature Summary
- Provides adjustable reference voltage functionality suitable for precision regulation applications
- Operates with low supply voltage requirements down to 2.5 V
- Delivers high cathode current capability for driving loads directly
Applications
- Battery-powered equipment requiring precise voltage monitoring
- Portable instruments needing stable reference voltages
- Power supply circuits utilizing shunt regulation topologies
Procurement Notes
Verify the specific suffix DBVR indicates tape-and-reel packaging when sourcing. Confirm the temperature grade corresponds to the industrial range (-40°C to +85°C) required for your design environment. Ensure the ±1.5% accuracy specification meets your circuit tolerance requirements before finalizing procurement decisions.
Selection Notes
Select this component when a low-voltage, adjustable shunt regulator is needed with moderate accuracy. Compare against the TLVH431B series if higher initial accuracy (±0.5%) is required. Consider the SOT-23-5 footprint constraints and ensure the 80 mA cathode current limit suffices for the intended load conditions.
Part Context
This part belongs to the TLVH431 family of low-voltage adjustable precision shunt regulators from Texas Instruments. It serves as a cost-effective alternative to traditional Zener diodes, offering superior temperature stability and lower dynamic impedance. The device integrates a bandgap reference and error amplifier within a compact five-pin package.
Replacement Considerations
The TLVH431IDBVT is a pin-compatible alternative available in cut-tape packaging instead of reel. For higher accuracy needs, the TLVH431BCDBVR offers ±0.5% initial accuracy but may require verification of thermal performance differences.
