Description and Introduction

TDA3664; Very low dropout voltage/quiescent current 5 V voltage regulator The TDA3664/N1 is a power supply IC manufactured by NXP Semiconductors. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** NXP  
- **Type:** Power Supply IC  
- **Package:** DIP (Dual In-line Package)  
- **Operating Voltage Range:** Typically used in SMPS (Switched-Mode Power Supply) applications  
- **Output Voltage:** Adjustable based on external components  
- **Switching Frequency:** High-frequency operation for efficient power conversion  
- **Protection Features:** Overvoltage protection, thermal shutdown  

### **Descriptions:**
The TDA3664/N1 is a monolithic integrated circuit designed for switched-mode power supply (SMPS) applications. It is commonly used in TV and monitor power supplies due to its efficiency and reliability. The IC integrates control functions and a power switch, reducing external component count.

### **Features:**
- Integrated high-voltage power switch  
- Built-in soft-start for reduced inrush current  
- Internal current limiting for overload protection  
- Low standby power consumption  
- Suitable for flyback converter topologies  

For exact electrical characteristics and application details, refer to the official NXP datasheet.

Application Scenarios & Design Considerations

TDA3664; Very low dropout voltage/quiescent current 5 V voltage regulator

Alternative Part Number

  • LM2936Z-5.0 --: Low-dropout 5V linear regulator in TO-92, functionally similar to the TDA3664 low-dropout regulator with comparable current capability.
  • MC33269D-5.0 --: 5V low-dropout regulator with similar dropout and current ratings, suitable drop-in replacement in many TDA3664 applications.
  • L4949EP --: 5V low-dropout automotive-grade regulator with similar voltage and current specifications, usable as an alternative with minor circuit review.
  • MC78L05ACPG --: Standard 5V 100mA linear regulator in TO-92 package, a common drop-in style replacement for low-current 5V regulation where the TDA3664 is used.
  • L78L05ACZ --: 5V 100mA fixed linear regulator in TO-92, broadly interchangeable for general-purpose 5V supply designs and easy to source as an alternative.
