Description and Introduction

800mA, Low Dropout Voltage Regulator The MC33269ST-3.3T3 is a voltage regulator manufactured by ON Semiconductor (formerly part of Motorola, hence the "MOT" designation).  

**Manufacturer:** ON Semiconductor (MOT)  

**Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 800mA  
- **Input Voltage Range:** 4.3V to 10V  
- **Dropout Voltage:** 1V (typical at full load)  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223  

**Descriptions:**  
The MC33269ST-3.3T3 is a low-dropout (LDO) voltage regulator designed for applications requiring stable and efficient power management. It features low quiescent current and thermal shutdown protection.  

**Features:**  
- Fixed 3.3V output  
- Low dropout voltage  
- High output current capability (800mA)  
- Thermal shutdown protection  
- Short-circuit protection  
- Low quiescent current  
- Stable with low-ESR capacitors  

This regulator is commonly used in automotive, industrial, and consumer electronics applications.

Application Scenarios & Design Considerations

800mA, Low Dropout Voltage Regulator

Alternative Part Number

  • LM1117S-3.3 --: Pin-compatible 3.3V low-dropout linear regulator in SOT-223 with similar current rating and widely available as a direct substitute.
  • AMS1117-3.3 --: Common 3.3V LDO regulator in SOT-223 package, electrically similar and often used as a drop-in replacement for MC33269 series.
  • LD1117S33TR --: 3.3V fixed LDO regulator in SOT-223 with comparable dropout and current specifications, suitable alternative from a different series.
