Description and Introduction

1A Low Dropout Regulator 3-DDPAK/TO-263 -40 to 125 The LM2940SX-9.0/NOPB is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. Below are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 9.0V  
- **Output Current:** Up to 1A  
- **Dropout Voltage:** Typically 0.5V at full load  
- **Input Voltage Range:** Up to 26V  
- **Line Regulation:** 0.3% (Typical)  
- **Load Regulation:** 0.4% (Typical)  
- **Quiescent Current:** 10mA (Typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-263 (D2PAK)  
- **Package Quantity:** Tape & Reel  

### **Descriptions:**
The LM2940SX-9.0/NOPB is a fixed-output LDO regulator designed to provide a stable 9.0V output with high accuracy. It is suitable for applications requiring low dropout voltage and high current capability. The device includes internal current limiting, thermal shutdown, and reverse battery protection.

### **Features:**
- **Low Dropout Voltage:** Ensures efficient regulation even when input voltage is close to output.  
- **Internal Current Limiting:** Protects the regulator from overcurrent conditions.  
- **Thermal Shutdown:** Prevents damage due to excessive temperature.  
- **Reverse Battery Protection:** Safeguards against reverse polarity connection.  
- **Low Quiescent Current:** Reduces power consumption in standby mode.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

This information is based solely on the manufacturer's datasheet.
