Description and Introduction

1.5A, Adjustable Output, Negative Voltage Regulator The LM337BT is a negative voltage regulator manufactured by STMicroelectronics (MOT).  

### **Specifications:**  
- **Output Voltage Range:** -1.2V to -37V  
- **Output Current:** Up to 1.5A  
- **Input-Output Voltage Differential (Max):** 40V  
- **Line Regulation:** 0.01%/V (Typ)  
- **Load Regulation:** 0.3% (Typ)  
- **Operating Junction Temperature Range:** 0°C to +125°C  
- **Package:** TO-220  

### **Descriptions:**  
The LM337BT is an adjustable negative voltage regulator designed to provide a stable output voltage with high accuracy. It requires only two external resistors to set the output voltage and includes built-in current limiting, thermal shutdown, and safe operating area protection.  

### **Features:**  
- Adjustable output voltage  
- 1.5A output current capability  
- Thermal overload protection  
- Short-circuit protection  
- Output transistor safe operating area protection  
- Low standby current  

This regulator is commonly used in power supply circuits requiring a negative voltage output.

Application Scenarios & Design Considerations

1.5A, Adjustable Output, Negative Voltage Regulator

Alternative Part Number

  • LM337T --: Same adjustable negative voltage regulator family in a TO-220 package, widely available and functionally equivalent to the original.
  • LT337AT --: Adjustable negative linear regulator with comparable electrical specifications and TO-220 package, suitable as a direct replacement.
  • MC337T --: Negative adjustable voltage regulator offering similar performance and pinout, a practical alternative from a different manufacturer series.
