- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-3  

### **Descriptions:**  
The TL432BIDBZR is a low-voltage, three-terminal adjustable shunt regulator with thermal stability and low dynamic impedance. It is designed for use in precision voltage regulation, voltage monitoring, and error amplification applications.  

### **Features:**  
- Adjustable output voltage with two external resistors  
- Low operating current (80µA typical)  
- Low output noise  
- Stable with capacitive loads  
- Improved accuracy over temperature (4mV typical)  
- Available in small SOT-23-3 package  

This device is commonly used in power supplies, battery chargers, and voltage reference circuits.

Application Scenarios & Design Considerations

Adjustable Precision Shunt Regulator

Alternative Part Number

  • LMV431AIM5 --: Adjustable shunt regulator in SOT-23-5 with 1.24V reference and 1% tolerance, functionally equivalent to TL432 and pin-compatible in most designs.
  • AZ432ANTR-G1 --: Low-voltage adjustable shunt regulator in SOT-23 with 1.25V reference, similar tolerance and current capability, suitable drop-in replacement.
  • TS432AILT --: Adjustable shunt voltage reference in SOT-23-3 with 1.25V reference and 0.5% tolerance, comparable electrical performance for TL432 applications.
