Overview
The TL432BIDBZRG4 is an adjustable precision shunt regulator manufactured by Texas Instruments. It provides a reference voltage range from 2.495 V to 36 V with an initial accuracy of ±0.5%. The device operates within a temperature range of -40 °C to +85 °C and features a maximum input voltage of 37 V. It supports a cathode current up to 100 mA and has a typical operating current of 80 µA. The component is housed in a surface-mount SOT-23-3 package.
Feature Summary
- Adjustable output voltage capability spanning 2.495 V to 36 V
- High initial accuracy of ±0.5% for precise regulation
- Low operating current consumption suitable for battery-powered applications
Applications
- Battery-powered equipment requiring stable voltage references
- Portable instruments needing low power consumption
- Power supply circuits utilizing shunt regulation topologies
Procurement Notes
Verify the specific suffix RG4 indicates tape and reel packaging when ordering. Confirm the BID variant corresponds to the ±0.5% accuracy grade required for the design. Ensure the SOT-23-3 footprint matches the PCB layout specifications. Check for RoHS compliance status if environmental regulations apply to the final assembly.
Selection Notes
Select this component when an adjustable reference with tighter tolerance than standard variants is needed. The ±0.5% accuracy distinguishes it from lower-grade options like the ID series. Consider the SOT-23-3 package size constraints against available board space. Evaluate the 100 mA cathode current limit against the maximum load requirements of the application circuit.
Part Context
This part belongs to the TL432 family of adjustable precision shunt regulators from Texas Instruments. It shares architectural similarities with the TL431 but offers adjustable output voltage rather than fixed levels. The family is designed for general-purpose voltage reference applications where space and power efficiency are critical factors in system design.
Replacement Considerations
The TL432IDBZR serves as a functional alternative with ±2.2% accuracy. Verify that the looser tolerance meets the circuit requirements before substitution. Both parts share the same SOT-23-3 pinout and electrical interface.
