Description and Introduction

LOW DROP FIXED AND ADJUSTABLE POSITIVE VOLTAGE REGULATORS The LD1117D33CTR is a low dropout voltage regulator manufactured by STMicroelectronics.  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 800mA  
- **Dropout Voltage:** Typically 1.1V at 800mA load  
- **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 (4-pin)  
- **Protection Features:** Overcurrent and thermal shutdown  

### **Descriptions and 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.  
- **High Accuracy:** Tight output voltage tolerance (±1%).  
- **Low Quiescent Current:** Improves efficiency in battery-powered applications.  
- **Thermal Overload Protection:** Safeguards the device from overheating.  
- **Short-Circuit Protection:** Enhances reliability in fault conditions.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  

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