Description and Introduction

800 mA LOW DROPOUT THREE-TERMINAL VOLTAGE REGULATORS The MC33269D-3.3 is a low-dropout (LDO) voltage regulator manufactured by Motorola (MOT).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** Up to 800mA  
- **Dropout Voltage:** Typically 1V at full load  
- **Input Voltage Range:** Up to 20V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 5mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-252 (DPAK)  

### **Features:**  
- **Low Dropout Voltage** for efficient power conversion  
- **Thermal Overload Protection** for safety  
- **Short-Circuit Protection** to prevent damage  
- **Stable with Low-ESR Capacitors** for reliable performance  
- **Internal Current Limiting** for enhanced durability  

This regulator is designed for applications requiring stable, low-noise power supplies, such as in automotive, industrial, and consumer electronics.

Application Scenarios & Design Considerations

800 mA LOW DROPOUT THREE-TERMINAL VOLTAGE REGULATORS

Alternative Part Number

  • LM1117DT-3.3 --: Pin-compatible 3.3V 800mA low-dropout linear regulator in TO-252/DPAK, widely available and a common drop-in replacement for the MC33269 series.
  • AMS1117-3.3 --: Very common 3.3V 1A LDO regulator in SOT-223/TO-252 packages with similar dropout and pinout, low cost and easy to source.
  • LD1117DT33TR --: 3.3V 800mA LDO regulator in DPAK with comparable electrical characteristics and pinout, suitable as a functional substitute.
