Description and Introduction

Series of Adjustable Micropower Voltage Regulators The LP2951CMM is a low-dropout voltage regulator manufactured by National Semiconductor (now part of Texas Instruments). Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage Options:** Fixed (3.0V, 3.3V, 5.0V) or Adjustable (1.24V to 29V)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 380mV (typical at 100mA load)  
- **Input Voltage Range:** Up to 30V  
- **Line Regulation:** 0.03% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC (CMM)  

### **Descriptions:**
- The LP2951CMM is a precision voltage regulator with very low dropout voltage, making it suitable for battery-powered applications.  
- It includes features like error flag output for low-voltage detection, thermal shutdown, and current limit protection.  
- Designed for stable operation with low-ESR capacitors.  

### **Features:**
- Low dropout voltage (380mV typical at 100mA)  
- Low quiescent current (75µA typical)  
- Adjustable or fixed output voltage options  
- Error flag warns of output dropout  
- Thermal shutdown and short-circuit protection  
- Stable with low-ESR capacitors (≥1µF)  
- Low noise operation  

This information is based on the manufacturer's datasheet. For detailed performance curves and application circuits, refer to the official documentation.
