Description and Introduction

300mA, Low Dropout Voltage Regulator The MC33275D-3.0 is a low-dropout (LDO) voltage regulator manufactured by Motorola (MOTO). Below are the specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 3.0V (Fixed)  
- **Output Current:** 250mA  
- **Dropout Voltage:** Typically 300mV at full load  
- **Input Voltage Range:** Up to 12V  
- **Line Regulation:** 0.05% (Typical)  
- **Load Regulation:** 0.1% (Typical)  
- **Quiescent Current:** 1.5mA (Typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC-8  

### **Descriptions:**  
- The MC33275D-3.0 is a precision LDO voltage regulator designed for applications requiring stable and low-noise power.  
- It includes built-in protection features such as thermal shutdown and current limiting.  
- Suitable for battery-powered devices, portable electronics, and embedded systems.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Enhances battery life in portable applications.  
- **Thermal Shutdown Protection:** Prevents damage due to overheating.  
- **Short-Circuit Protection:** Safeguards the regulator and load.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  

This information is based solely on the manufacturer's datasheet for the MC33275D-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 with similar current rating and pinout, widely available and a common drop-in substitute.
  • LP2950ACZ-3.0 --: 3.0V low-dropout regulator in TO-92, low quiescent current, suitable replacement for low-power applications of the original.
  • L78L30ACZ --: 3.0V fixed linear regulator in TO-92 with standard pinout, a simple and inexpensive alternative for non-critical LDO needs.
  • UA78L30ACLP --: 3.0V fixed positive voltage regulator in TO-92, a standard legacy alternative suitable for low-current 3.0V regulation.
