Description and Introduction

100mA Low Dropout Voltage Regulator The LM2931 is a low-dropout voltage regulator manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** Up to 26V  
- **Output Voltage Options:** Fixed (3.3V, 5V, 12V, 15V) or Adjustable (1.24V to 26V)  
- **Output Current:** Up to 100mA  
- **Dropout Voltage:** Typically 0.4V at 100mA load  
- **Quiescent Current:** Typically 1mA (with low-power mode available)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Accuracy:** ±2% (for fixed output versions)  
- **Package Options:** TO-220, TO-92, SOT-223, SOIC-8  

### **Descriptions:**
- The LM2931 is designed for battery-powered applications requiring low dropout voltage and low quiescent current.  
- It includes reverse battery protection, thermal shutdown, and current limiting for enhanced reliability.  
- Suitable for automotive and industrial applications due to its wide input voltage range and rugged design.  

### **Features:**
- **Low Dropout Voltage:** Ensures stable output even with small input-output differentials.  
- **Reverse Polarity Protection:** Safeguards against incorrect battery connections.  
- **Thermal Shutdown:** Prevents damage from excessive heat.  
- **Current Limiting:** Protects the regulator and load from overcurrent conditions.  
- **Low Quiescent Current:** Extends battery life in standby modes.  
- **Adjustable Output (for some variants):** Allows flexibility in setting the desired output voltage.  

This information is based on TI's official documentation for the LM2931 voltage regulator.
