Description and Introduction

NEGATIVE VOLTAGE REGULATORS The **L7912CP** is a negative voltage regulator manufactured by **STMicroelectronics (ST)**. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** -12V  
- **Output Current:** Up to 1.5A  
- **Input Voltage Range:** -14.5V to -35V (for -12V output)  
- **Dropout Voltage:** 2V (typical)  
- **Line Regulation:** 0.1% (typical)  
- **Load Regulation:** 0.3% (typical)  
- **Operating Temperature Range:** 0°C to +125°C  
- **Package:** TO-220 (3 pins)  

### **Descriptions:**
- The **L7912CP** is a fixed **negative voltage regulator** designed to provide a stable -12V output.  
- It includes **internal thermal overload protection**, **short-circuit protection**, and **safe operating area (SOA) protection**.  
- Suitable for applications requiring a regulated negative voltage supply.  

### **Features:**
- **Fixed -12V output** with high accuracy.  
- **Thermal shutdown** prevents overheating.  
- **Short-circuit protected** with current limiting.  
- **Low noise** and **low ripple** output.  
- **No external components** required for basic operation (except input/output capacitors).  

This regulator is commonly used in power supply circuits for analog and digital systems requiring a stable negative voltage rail.
