Overview
The TLVH431AMQDBZR,215 is a low voltage three-terminal adjustable precision shunt regulator from the TLVH431 family. It operates with a cathode-anode voltage range of 1 V to 18 V and supports a sink current capability from 0.08 mA to 70 mA. The device features an A-Grade reference voltage tolerance of 1%, with a typical reference voltage of 1240 mV at 25 °C. It utilizes a SOT23 package with mirrored pinning configuration and is qualified to AEC-Q100 Grade 1 standards for automotive applications.
Feature Summary
- AEC-Q100 qualified for Grade 1 automotive environments
- Mirrored pinning configuration in SOT23 package
- Low output noise and high stability
- Adjustable output voltage via external resistors
Applications
- Shunt regulator
- Precision current limiter
- Precision constant current sink
- Isolated feedback loop for Switch Mode Power Supply (SMPS)
Procurement Notes
Verify that the specific part number includes the MQ suffix to confirm the mirrored pinning configuration required for your PCB layout. Ensure the design accounts for the A-Grade 1% reference voltage tolerance specifications. Confirm the component meets AEC-Q100 Grade 1 requirements if deployed in automotive systems. Cross-reference the SOT23 footprint dimensions against your manufacturing capabilities.
Selection Notes
Select this component when a mirrored pinout is necessary within a compact SOT23 form factor. The A-Grade tolerance provides tighter accuracy than standard grades. Verify compatibility with the required operating temperature range of -40 °C to 125 °C. Consider the low output impedance characteristics for stable regulation in sensitive analog circuits.
Part Context
This device belongs to the TLVH431 family of low voltage adjustable precision shunt regulators manufactured by NXP Semiconductors. The family offers various reference voltage tolerances and packaging options to suit different application needs. The TLVH431 series is designed to replace Zener diodes in on-board regulation and switching power supply designs.
Replacement Considerations
Standard pinning equivalents include TLVH431AQDBZR. Other family members like TLVH431DQDBZR offer tighter 0.75% tolerance but lack the mirrored pinout.
