Description and Introduction

300mA, Low Dropout Voltage Regulator The MC33275DT-3.0 is a low-dropout (LDO) voltage regulator manufactured by Motorola (MOTO).  

### **Specifications:**  
- **Output Voltage:** 3.0V (fixed)  
- **Output Current:** Up to 250mA  
- **Dropout Voltage:** Typically 0.4V at full load  
- **Input Voltage Range:** Up to 12V  
- **Low Quiescent Current:** Typically 75µA  
- **Thermal Shutdown Protection:** Yes  
- **Short-Circuit Protection:** Yes  
- **Package Type:** TO-252 (DPAK)  

### **Descriptions and Features:**  
- Designed for battery-powered applications requiring stable voltage regulation.  
- Low dropout voltage ensures efficient operation even when input voltage is close to the output.  
- Internal protection features include thermal shutdown and current limiting.  
- Suitable for portable electronics, embedded systems, and power management applications.  
- Stable with low-ESR ceramic capacitors.  

This information is based on Motorola's datasheet for the MC33275DT-3.0.

Application Scenarios & Design Considerations

300mA, Low Dropout Voltage Regulator

Alternative Part Number

  • LM2937ET-3.0 --: Low-dropout 3.0V linear regulator in TO-220, similar current capability and pinout, widely available and a common drop-in substitute for the MC33275 series.
  • LP2950ACZ-3.0 --: 3.0V low-dropout regulator in TO-92 with comparable dropout and quiescent current, suitable for low-power applications replacing the MC33275DT-3.0.
  • L78L30ACZ --: 3.0V fixed linear regulator in TO-92, simple three-terminal alternative when dropout requirements are modest and a low-cost standard regulator is acceptable.
