Description and Introduction

VERY LOW DROP VOLTAGE REGULATORS WITH INHIBIT The LD2979M33 is a low-dropout (LDO) voltage regulator manufactured by STMicroelectronics. Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 500mA  
- **Dropout Voltage:** 300mV (typical at 500mA)  
- **Input Voltage Range:** 4.5V to 15V  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 6mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-252 (DPAK)  

### **Descriptions:**
- The LD2979M33 is a positive voltage regulator designed to provide a stable 3.3V output from an input voltage as high as 15V.  
- It features low dropout voltage, making it suitable for battery-powered applications.  
- Includes internal current limiting and thermal shutdown protection.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient regulation even when the input voltage is close to the output.  
- **Thermal Protection:** Prevents damage due to overheating.  
- **Short-Circuit Protection:** Safeguards the regulator and connected components.  
- **Wide Input Voltage Range:** Supports various power supply configurations.  
- **Stable with Low-ESR Capacitors:** Ensures reliable performance without requiring additional components.  

This regulator is commonly used in automotive, industrial, and consumer electronics applications.
