Description and Introduction

Low drop fixed positive voltage regulator, 3.3V The LD1117S33C is a low dropout voltage regulator manufactured by STMicroelectronics (ST).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 800mA  
- **Dropout Voltage:** 1.2V (typical at 800mA)  
- **Input Voltage Range:** Up to 15V  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223  

### **Descriptions & Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Fixed Output Voltage:** Pre-set to 3.3V, eliminating the need for external resistors.  
- **Overcurrent & Thermal Protection:** Built-in safeguards against excessive current and overheating.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  
- **Low Quiescent Current:** Enhances efficiency in battery-powered applications.  

This regulator is commonly used in power supply circuits for microcontrollers, embedded systems, and other low-voltage applications.
