TL432BIDBZTG4

Overview

The TL432BIDBZTG4 is an adjustable precision shunt regulator manufactured by Texas Instruments, housed in a SOT-23-3 surface-mount package. It features an initial accuracy of ±0.5% and operates within a temperature range of -40°C to +85°C. The device supports an adjustable output voltage from 2.495V to 36V with a maximum input voltage of 37V. It can sink a cathode current up to 100mA, with a minimum operating current of 600µA.

Feature Summary

• Provides high-precision voltage regulation with ±0.5% initial accuracy for stable reference applications
• Offers wide adjustable output voltage range from 2.495V to 36V using external resistors
• Features low dynamic output impedance and low noise characteristics for clean signal integrity

Applications

• Precision voltage references in power supply circuits
• Programmable linear regulators requiring stable reference nodes
• Battery-operated equipment needing accurate voltage monitoring

Procurement Notes

Verify the suffix TG4 indicates RoHS compliance and green material status as per Texas Instruments documentation. Confirm the SOT-23-3 package type matches the design footprint requirements. Ensure the ±0.5% accuracy grade meets the specific circuit tolerance needs. Check for any recent Product Change Notifications regarding marking or packaging updates.

Selection Notes

Select this component when a compact SOT-23-3 form factor is required alongside tight ±0.5% accuracy specifications. It is suitable for designs needing an adjustable reference up to 36V with moderate current sinking capabilities. Consider thermal dissipation limits if operating near maximum current ratings in enclosed spaces.

Part Context

This part belongs to the TL432 family of three-terminal programmable shunt regulators from Texas Instruments. It shares functional similarities with the TL431 but is optimized for surface-mount applications. The series provides various accuracy grades and packages to support diverse industrial and commercial power management designs.

Replacement Considerations

TL432BIDBZT is a direct equivalent without the TG4 suffix. NCP431ACSNT1G and NCP431AISNT1G are listed as similar alternatives from onsemi.
