Description and Introduction

1.5A Adjustable Negative Voltage Regulator The LM337K is a negative voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage Range:** -1.2V to -37V  
- **Output Current:** Up to 1.5A  
- **Line Regulation:** 0.01%/V (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Dropout Voltage:** 1.5V (typical at 1A)  
- **Operating Junction Temperature:** 0°C to +125°C  
- **Package:** TO-3 (Metal Can)  

### **Descriptions:**  
- The LM337K is an adjustable negative voltage regulator designed to supply a load current of up to 1.5A.  
- It requires only two external resistors to set the output voltage.  
- Features internal current limiting, thermal shutdown, and safe operating area protection.  

### **Features:**  
- **Adjustable Output:** The output voltage can be set using external resistors.  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Short-Circuit Protection:** Safeguards the regulator from output short circuits.  
- **High Ripple Rejection:** Reduces input voltage fluctuations.  
- **Stable with Low-ESR Capacitors:** Works efficiently with inexpensive capacitors.  

This information is based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

1.5A Adjustable Negative Voltage Regulator

Alternative Part Number

  • LT337MK --: Same TO-3 metal-can negative adjustable regulator with equivalent -1.2V to -37V range and 1.5A rating; high reliability and direct pin-compatible replacement.
  • MC337T --: Classic TO-3 negative adjustable voltage regulator functionally equivalent to LM337K, widely available and pin-compatible.
  • SG337K --: TO-3 packaged negative adjustable regulator with comparable electrical specifications, suitable as a drop-in substitute for the LM337K.
  • LM337KC --: Same negative adjustable regulator family in a TO-3 package, widely available and electrically compatible with the LM337K.
  • LT337K --: Direct negative adjustable regulator equivalent from Linear Technology's own LT series, offering similar voltage and current ratings.
  • MC337K --: Industry-standard negative adjustable regulator in TO-3 package, pin-compatible and functionally equivalent to the LM337K.
