Overview
The TLVH432AIDBZR is a low-voltage adjustable precision shunt regulator manufactured by Texas Instruments. It operates within an output voltage range of 1.24 V to 18 V and provides an initial accuracy of ±1%. The device supports a cathode current of up to 70 mA and functions reliably across a temperature range of -40°C to +125°C. Packaged in a SOT-23-3 surface-mount case, it serves as a high-performance reference for power management applications.
Feature Summary
- Adjustable output voltage capability from 1.24 V to 18 V via external resistors
- High initial accuracy with ±1% tolerance at 25°C
- Robust thermal stability over extended industrial temperature ranges
Applications
- Low-voltage adjustable precision shunt regulation
- Secondary side voltage regulation in switch-mode power supplies
- Replacement for Zener diodes in board-level稳压 circuits
Procurement Notes
Verify the specific suffix DBZR corresponds to the SOT-23-3 tape-and-reel packaging configuration required for automated assembly. Confirm that the ±1% accuracy grade meets the design specifications for the target application's voltage reference requirements before finalizing procurement orders.
Selection Notes
Select this component when a low-voltage adjustable reference is needed with higher accuracy than standard Zener diodes. The SOT-23-3 package suits space-constrained designs. Ensure the maximum cathode current of 70 mA aligns with the circuit's biasing needs and that the 18 V maximum output fits the system voltage constraints.
Part Context
This part belongs to the TLVH432 family of low-voltage adjustable precision shunt regulators. It shares functional similarities with the TLV431 but offers distinct electrical characteristics optimized for lower voltage operations. The device integrates a bandgap reference and error amplifier to maintain stable output voltages under varying load conditions.
FAQ
What is the minimum operating voltage for the TLVH432AIDBZR?
The minimum reference input voltage is approximately 1.24 V, which also serves as the minimum adjustable output voltage.
Does the TLVH432AIDBZR include a shutdown feature?
No, the TLVH432AIDBZR does not have a dedicated shutdown pin or function; it operates continuously once powered above the minimum threshold.
