Description and Introduction

Very low dropout voltage/quiescent current 3.3 V voltage regulator The TDA3663 is a voltage regulator manufactured by PHILIPS (now NXP Semiconductors). Below are its key specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 5.5V to 18V  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** Up to 1A  
- **Dropout Voltage:** Typically 1V at 1A  
- **Line Regulation:** ±0.2% (typical)  
- **Load Regulation:** ±0.5% (typical)  
- **Quiescent Current:** 6mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-220 (5-pin)  

### **Descriptions:**
- The TDA3663 is a monolithic integrated voltage regulator designed for automotive and industrial applications.  
- It provides a stable 5V output from an input voltage range of 5.5V to 18V.  
- The device includes built-in protection features such as thermal shutdown, short-circuit protection, and reverse polarity protection.  

### **Features:**
- **Fixed 5V Output:** Ensures stable voltage supply.  
- **High Current Capability:** Supports up to 1A output current.  
- **Low Dropout Voltage:** Efficient operation with minimal voltage loss.  
- **Thermal Protection:** Prevents overheating damage.  
- **Short-Circuit Protection:** Safeguards against output shorts.  
- **Reverse Polarity Protection:** Protects against incorrect power supply connections.  
- **Wide Operating Temperature Range:** Suitable for harsh environments.  

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

Application Scenarios & Design Considerations

Very low dropout voltage/quiescent current 3.3 V voltage regulator

Alternative Part Number

  • LM2936Z-5.0 --: Low-dropout 5V linear regulator in TO-92, similar function and package to the TDA3663; widely available and pin-compatible in most applications.
  • MC78L05ACPG --: Standard 5V/100mA linear regulator in TO-92, a common drop-in substitute for low-current 5V regulation where dropout is not critical.
  • L78L05ACZ --: 5V/100mA fixed linear regulator in TO-92, low-cost and broadly stocked alternative for general 5V supply replacement.
