Description and Introduction

800mA, Low Dropout Voltage Regulator The MC33269T is a voltage regulator manufactured by Motorola. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Motorola  
- **Type:** Low Dropout Voltage Regulator  
- **Output Voltage Options:** Fixed (e.g., 3.3V, 5V, etc.) or Adjustable  
- **Output Current:** Up to 800mA  
- **Dropout Voltage:** Typically 1V at full load  
- **Input Voltage Range:** Up to 20V  
- **Line Regulation:** Typically 0.02%  
- **Load Regulation:** Typically 0.04%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package Type:** TO-220  

### **Descriptions:**
- The MC33269T is a linear voltage regulator designed for applications requiring stable power supply with low dropout voltage.  
- It includes built-in protection features such as thermal shutdown and current limiting.  
- Suitable for automotive, industrial, and consumer electronics applications.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Shutdown Protection:** Prevents damage due to overheating.  
- **Current Limiting:** Protects the regulator and load from excessive current.  
- **High Ripple Rejection:** Reduces noise in the output voltage.  
- **Fixed or Adjustable Output:** Available in different voltage configurations.  

This information is based on Motorola's official documentation for the MC33269T. For exact details, refer to the manufacturer's datasheet.

Application Scenarios & Design Considerations

800mA, Low Dropout Voltage Regulator

Alternative Part Number

  • LM317T --: Widely available adjustable positive voltage regulator in TO-220, similar current capability and function, easy drop-in for many MC33269T applications.
  • LM1117T-ADJ --: Low-dropout adjustable regulator in TO-220 with comparable current rating, often used as a modern replacement for older LDO regulators.
  • LT1086CT --: Adjustable LDO regulator in TO-220 with similar voltage and current specifications, suitable when lower dropout and better performance are needed.
  • L78S05CV --: Fixed 5V positive regulator in TO-220 with similar package and current capability, suitable if a fixed 5V output is acceptable.
