Description and Introduction

1A Low Dropout Regulator The LM2940LDX-8.0 is a low-dropout (LDO) voltage regulator manufactured by Texas Instruments. Below are the key specifications, descriptions, and features based on factual data:  

### **Manufacturer:** Texas Instruments  

### **Specifications:**  
- **Output Voltage:** 8.0V (fixed)  
- **Output Current:** Up to 1A  
- **Dropout Voltage:** Typically 0.5V at full load (1A)  
- **Input Voltage Range:** Up to 26V  
- **Line Regulation:** 0.04% (typical)  
- **Load Regulation:** 0.2% (typical)  
- **Quiescent Current:** 10mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-252 (DPAK)  

### **Descriptions:**  
- The LM2940LDX-8.0 is a fixed-output LDO regulator designed to provide a stable 8.0V output with low dropout voltage.  
- It includes built-in protection features such as thermal shutdown and current limiting.  
- Suitable for battery-powered applications due to its low quiescent current.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Short-Circuit Protection:** Safeguards against output shorts.  
- **Reverse Battery Protection:** Protects against reverse polarity.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.
