Overview
The TL432ACDBZRG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a supply voltage range of 2.495 V to 36 V and provides an initial accuracy of 1%. The device supports a maximum cathode current of 100 mA with a minimum operating current of 600 µA. It features a temperature coefficient of 92 ppm/°C and functions across an extended temperature range from -40°C to +125°C. The component is housed in a surface-mount SOT-23-3 package.
Feature Summary
- Provides stable reference voltage through adjustable shunt regulation topology
- Delivers high precision performance with 1% initial accuracy specification
- Operates reliably across extended industrial temperature ranges
Applications
- Portable equipment power supplies
- Battery-powered systems requiring precise voltage references
- General-purpose voltage regulation circuits
Procurement Notes
Verify the complete part number including the RG4 suffix to ensure correct tape-and-reel packaging configuration. Confirm RoHS compliance status and lead times directly with authorized distributors or Texas Instruments. Ensure the ordering quantity matches the required reel specifications for surface-mount assembly processes.
Selection Notes
Select this component when a compact, low-cost adjustable reference is needed for space-constrained designs. The SOT-23-3 package offers a small footprint suitable for dense PCB layouts. Consider the 1% accuracy and 92 ppm/°C temperature coefficient for applications requiring moderate stability without the cost of higher-grade references.
Part Context
This device belongs to the TL432 family of adjustable shunt regulators, which are widely used as voltage references in power management applications. It serves as a three-terminal alternative to fixed voltage references, allowing designers to set output voltages using external resistors while maintaining precision and stability in compact packages.
Replacement Considerations
Check for pin-compatible alternatives such as the TL431 series if additional pins are available, though electrical characteristics may differ. Verify that any substitute maintains the same SOT-23-3 package and meets the 1% accuracy requirement.
