Description and Introduction

800 mA, Adjustable Output, Low Dropout Voltage Regulator The MC33269T-3.3G is a voltage regulator manufactured by Motorola (MOTO). Here are its specifications, descriptions, and features:

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

### **Descriptions:**
- The MC33269T-3.3G is a low-dropout (LDO) voltage regulator designed for applications requiring a stable 3.3V supply.  
- It features internal current limiting and thermal shutdown protection.  
- Suitable for battery-powered and industrial applications.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Current Limiting:** Protects the regulator and load from overcurrent conditions.  
- **High Accuracy:** Provides precise voltage regulation.  
- **Wide Input Voltage Range:** Supports a broad range of input sources.  

This information is based on the manufacturer's datasheet.

Application Scenarios & Design Considerations

800 mA, Adjustable Output, Low Dropout Voltage Regulator

Alternative Part Number

  • LM1117T-3.3 --: Pin-compatible 3.3V 800mA LDO regulator in TO-220, widely available and a common drop-in replacement for the MC33269 series.
  • LD1117V33 --: 3.3V 800mA low-dropout regulator in TO-220 with the same pinout and comparable electrical characteristics.
  • AMS1117-3.3 --: Low-cost 3.3V 1A LDO regulator in TO-220, functionally equivalent for most applications though with slightly different dropout and tolerance specs.
