Overview
The TLVH431NAIDBZRR is a three-terminal adjustable precision shunt regulator from the Nexperia TLVH431N family, housed in an SOT23 surface-mounted package. It features A-Grade reference voltage tolerance of 1.0%, with a typical reference voltage of 1240 mV at 25 °C. The device supports programmable output voltages ranging from approximately 1.24 V to 14 V via external resistors. Recommended operating conditions specify a cathode-anode voltage up to 14 V and a sink current capability between 0.08 mA and 70 mA.
Feature Summary
- Programmable output voltage range extending up to 14 V
- Low output noise characteristics
- Typical dynamic output impedance of 0.1 Ω
- Active output circuitry providing sharp turn-on
Applications
- Shunt regulator circuits
- Precision constant current sinks
- Isolated feedback loops for Switch Mode Power Supplies (SMPS)
- Precision current limiters
Procurement Notes
Verify that the specific ordering suffix matches the required pinning configuration, as mirrored pinning variants exist within the family. Confirm the temperature grade corresponds to the intended operational environment. Ensure design compliance with absolute maximum ratings regarding power dissipation and junction temperature limits during integration.
Selection Notes
Select this component when low noise and high precision are required for voltage referencing or regulation. The A-Grade variant offers tighter tolerance compared to standard grades. Verify thermal stability requirements against the specified ambient temperature range. Consider the SOT23 package constraints for PCB layout and heat dissipation capabilities.
Part Context
This part belongs to the TLVH431N family of adjustable precision shunt regulators. The family includes variants with different reference voltage tolerances and temperature ranges. The 'A' designation indicates the 1.0% tolerance grade, while 'I' specifies the industrial temperature range. The 'RR' suffix typically denotes reel packaging for automated assembly.
Replacement Considerations
Direct replacements include other TLVH431N family members such as TLVH431NAIDBZR, provided pinning configurations match. Cross-family substitutes like TL431 series devices may require verification of reference voltage accuracy and operating current ranges.
