Description and Introduction

Adjustable Precision Shunt Regulator The TL432QDBZR is a precision low-voltage adjustable shunt regulator manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Voltage Range:** 1.24V to 6V  
- **Reference Voltage:** 1.24V (typical)  
- **Operating Current Range:** 60µA to 15mA  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Temperature Stability:** 50ppm/°C (typical)  
- **Package:** SOT-23-3  
- **Operating Temperature Range:** -40°C to +125°C  

### **Descriptions:**  
The TL432QDBZR is a three-terminal adjustable shunt regulator with thermal stability, low dynamic impedance, and low output noise. It is designed to replace fixed-voltage regulators in applications requiring adjustable voltage references.  

### **Features:**  
- Adjustable output voltage  
- Low operating current (60µA typical)  
- Low output impedance (0.2Ω typical)  
- Stable with low-ESR capacitors  
- Wide operating temperature range  
- Available in a small SOT-23-3 package  

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

Application Scenarios & Design Considerations

Adjustable Precision Shunt Regulator

Alternative Part Number

  • LMV431AIM5/NOPB --: Adjustable shunt regulator with 1.24V reference in SOT-23-5, functionally similar to TL432 and widely available from TI.
  • AZ432ANTR-G1 --: 1.25V adjustable shunt regulator in SOT-23, direct functional replacement for TL432 with comparable tolerance and current capability.
  • TS432ILT --: Adjustable shunt voltage reference in SOT-23-3 with 1.25V reference, suitable alternative when a different package pinout is acceptable.
