Description and Introduction

VERY LOW DROP VOLTAGE REGULATOR WITH INHIBIT The LD2979M33TR is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 800mA  
- **Dropout Voltage:** 0.5V (typical) at full load  
- **Input Voltage Range:** Up to 16V  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 6mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223  

### **Descriptions:**  
- The LD2979M33TR is a positive voltage regulator designed to provide a stable 3.3V output with high accuracy.  
- It features low dropout voltage, making it suitable for battery-powered applications.  
- Includes built-in thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Protection:** Prevents damage due to overheating.  
- **Current Limiting:** Protects the regulator and load from excessive current.  
- **Wide Input Voltage Range:** Supports applications with varying input supplies.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

This information is based on the manufacturer's datasheet. For detailed electrical characteristics and application notes, refer to STMicroelectronics' official documentation.
