Description and Introduction

Very low drop voltage regulators with inhibit function The LM2931AD33R is a low-dropout voltage regulator manufactured by STMicroelectronics. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 100mA  
- **Dropout Voltage:** 0.4V (typical at full load)  
- **Input Voltage Range:** 4.5V to 26V  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 1mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SO-8  

### **Descriptions:**
- The LM2931AD33R is a low-dropout linear regulator designed for applications requiring stable 3.3V power supply.  
- It features 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 robust performance.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Reverse Battery Protection:** Safeguards the regulator from damage due to incorrect polarity.  
- **Thermal Shutdown:** Prevents overheating by shutting down the regulator if the temperature exceeds safe limits.  
- **Current Limiting:** Protects the regulator and load from excessive current.  
- **Wide Input Voltage Range:** Supports operation from 4.5V to 26V, making it versatile for various applications.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

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