Overview
The TL432CDBVRG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It operates within a voltage range of 2.495 V to 36 V and features an initial accuracy of 2%. The device has a temperature coefficient of 34 PPM/C and supports a maximum shunt current of 100 mA with a minimum cathode current of 600 uA. It functions in an industrial temperature range from 0°C to +70°C and utilizes a SOT-23-5 surface-mount package.
Feature Summary
- Provides adjustable reference voltage output across a wide operational range
- Delivers high precision regulation with low temperature drift characteristics
- Supports high current sinking capability for robust power management applications
Applications
- Portable equipment power supply regulation
- DC-to-DC converter feedback loops
- Battery chargers and power adapters
Procurement Notes
Verify the specific suffix G4 indicates lead-free and RoHS compliance status against the manufacturer's latest documentation. Confirm the SOT-23-5 package marking and pinout configuration matches the design requirements. Ensure the operating environment remains within the specified 0°C to +70°C thermal limits for reliable performance.
Selection Notes
Select this component when a compact, adjustable shunt regulator with 2% initial accuracy is required. It serves as a direct replacement for standard TL431 devices where higher precision or specific package constraints are necessary. Verify that the 100 mA sink current meets the circuit load demands and that the 36 V maximum input voltage aligns with the system supply rails.
Part Context
This part belongs to the TL432 family of adjustable precision shunt regulators from Texas Instruments. It shares functional similarities with the TL431 series but offers distinct package and performance variations. The device is categorized under PMIC voltage references and is designed for general-purpose voltage regulation tasks in consumer and industrial electronics.
Replacement Considerations
The TL432CDBVR is a non-RoHS equivalent variant. The TL432BCDBVRG4 offers improved 0.5% accuracy. Verify pin compatibility and electrical specifications before substituting with other adjustable shunt regulators.
