Description and Introduction

1 A Three-Terminal Positive Voltage Regulator The TA7805AF is a fixed positive voltage regulator manufactured by Toshiba. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** +5V (fixed)  
- **Output Current:** 1A (max)  
- **Input Voltage Range:** Up to 35V  
- **Dropout Voltage:** 2V (typical)  
- **Line Regulation:** 100mV (typical)  
- **Load Regulation:** 100mV (typical)  
- **Operating Temperature Range:** -30°C to +85°C  
- **Package Type:** TO-220F (isolated tab)  

### **Descriptions:**
- The TA7805AF is a 3-terminal voltage regulator designed to provide a stable +5V output.  
- It includes built-in overcurrent protection, thermal shutdown, and safe operating area (SOA) protection.  
- Suitable for power supply applications requiring a fixed +5V output.  

### **Features:**
- **Fixed Output Voltage:** Ensures a stable +5V supply.  
- **Overcurrent Protection:** Safeguards against excessive current draw.  
- **Thermal Shutdown:** Prevents damage due to overheating.  
- **High Ripple Rejection:** Reduces input noise effectively.  
- **Isolated Tab (TO-220F):** Simplifies heat sink mounting.  

This information is based on Toshiba's official documentation for the TA7805AF.

Application Scenarios & Design Considerations

1 A Three-Terminal Positive Voltage Regulator

Alternative Part Number

  • L7805ACD2T-TR --: Widely available 5V linear regulator in TO-252 (DPAK) package with similar current rating and pinout, direct functional replacement for the TA7805AF.
  • MC7805CD2TG --: Industry-standard 5V positive voltage regulator in DPAK package, well-stocked and electrically compatible with the original Toshiba part.
  • LM7805CT --: Classic 5V regulator in TO-220 package; use if board space allows, offers excellent availability and proven reliability as an alternative.
  • MC7805CTG --: 5V fixed linear regulator with same TO-220 package and pinout, direct functional replacement.
  • L7805CV --: Common 5V regulator in TO-220, electrically and mechanically compatible with the original part.
