Description and Introduction

800 mA LOW DROPOUT THREE-TERMINAL VOLTAGE REGULATORS The MC33269T-3.3 is a low-dropout (LDO) voltage regulator manufactured by Motorola (now part of ON Semiconductor). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 800mA (maximum)  
- **Dropout Voltage:** Typically 1V at full load (800mA)  
- **Input Voltage Range:** 4.3V to 20V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 5mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-220 (3-pin)  

### **Descriptions:**
- The MC33269T-3.3 is a fixed-output LDO voltage regulator designed for applications requiring stable and efficient power regulation.  
- It provides a constant 3.3V output with high accuracy and low dropout voltage, making it suitable for battery-powered and noise-sensitive systems.  
- Includes built-in thermal shutdown and current limiting for protection against overheating and short circuits.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **High Output Accuracy:** Tight tolerance (±2%) over line and load variations.  
- **Thermal Protection:** Automatic shutdown in case of excessive temperature.  
- **Current Limiting:** Protects the regulator and load from overcurrent conditions.  
- **Wide Input Voltage Range:** Supports operation from 4.3V up to 20V.  
- **Low Quiescent Current:** Enhances efficiency in battery-operated applications.  

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