Description and Introduction

Output Current of 0.5 A, Three-Terminal Positive Voltage Regulators 18V The TA78M18F is a positive voltage regulator manufactured by Toshiba. Below are its key specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage:** +18V (fixed)  
- **Output Current:** 500mA (max)  
- **Input Voltage Range:** Up to 35V  
- **Dropout Voltage:** 2V (typical at 500mA)  
- **Line Regulation:** 100mV (typical)  
- **Load Regulation:** 150mV (typical)  
- **Operating Temperature Range:** -30°C to +85°C  
- **Package Type:** TO-220F (fully molded)  

### **Descriptions:**  
- The TA78M18F is a monolithic integrated circuit designed as a fixed positive voltage regulator.  
- It includes built-in overcurrent protection, thermal shutdown, and safe operating area protection.  
- Suitable for applications requiring stable +18V power supply.  

### **Features:**  
- **Overcurrent Protection:** Prevents damage due to excessive load current.  
- **Thermal Shutdown:** Automatically disables output if overheating occurs.  
- **High Ripple Rejection:** Reduces input voltage fluctuations.  
- **Low Standby Current:** Improves efficiency in standby mode.  
- **No External Components Required:** Simplifies circuit design.  

This information is strictly factual and sourced from Toshiba's documentation.
