Description and Introduction

1A Low Dropout Regulator for 5V to 3.3V Conversion 3-DDPAK/TO-263 -40 to 125 The LM3940IS-3.3/NOPB is a low-dropout voltage regulator manufactured by Texas Instruments (formerly National Semiconductor, NS).  

### **Specifications:**  
- **Output Voltage:** 3.3V  
- **Maximum Input Voltage:** 7V  
- **Output Current:** 1A  
- **Dropout Voltage:** 0.5V (typical at 1A)  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.04% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  
- **Mounting Type:** Surface Mount  

### **Descriptions and Features:**  
- Designed for low-dropout applications requiring up to 1A of current.  
- Includes thermal shutdown and current limit protection.  
- Stable with low-ESR capacitors (≥10μF recommended).  
- Low quiescent current (10mA typical).  
- Suitable for battery-powered and industrial applications.  
- Pb-free (RoHS compliant).  

This regulator is commonly used in power supply circuits for microcontrollers, FPGAs, and other digital systems requiring a stable 3.3V supply.
