Overview
The TLV431CDBZRG4 is an adjustable precision shunt voltage reference from Texas Instruments, housed in a SOT-23-3 surface-mount package. It operates within a cathode voltage range of 2.5 V to 36 V and provides an adjustable output voltage between 1.24 V and 36 V. The device features an initial accuracy of ±1.5% and a maximum temperature coefficient of 92 ppm/°C. It supports a maximum cathode current of 100 mA with a minimum operating current of 600 µA. The component functions reliably across an industrial temperature range of 0°C to +70°C.
Feature Summary
- Provides stable adjustable reference voltage for precision circuit applications
- Operates over a wide input voltage range up to 36 V
- Delivers high initial accuracy for reliable regulation performance
Applications
- Portable equipment power management
- DC-to-DC converter feedback loops
- Battery-powered system voltage monitoring
Procurement Notes
Verify the specific suffix 'G4' indicates RoHS compliance and lead-free construction as per Texas Instruments standards. Confirm the SOT-23-3 package type matches your PCB footprint requirements. Ensure the ±1.5% accuracy class meets your design tolerance specifications before finalizing procurement orders.
Selection Notes
Select this component when a low-cost, high-current adjustable reference is required for industrial temperature ranges. Compare against the TLV431B variant if tighter ±0.5% accuracy is necessary. Consider the TLV431A series if lower temperature coefficients are critical for your thermal environment.
Part Context
This part belongs to the TLV431 family of adjustable shunt regulators designed for general-purpose voltage referencing. It serves as a cost-effective alternative to fixed references in applications requiring programmable output voltages. The device integrates a bandgap reference and error amplifier within a compact three-terminal package.
Replacement Considerations
The TLV431BCDBZR is listed as a manufacturer-recommended replacement for the discontinued TLV431BCDBZRG4. Verify pinout compatibility and electrical parameter alignment before substituting.
