Description and Introduction

120mA High Efficiency Step-Down Switched Capacitor Voltage Converter The LM2788MM-1.5 is a fixed-output voltage regulator manufactured by National Semiconductor (NS). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Output Voltage:** 1.5V (fixed)  
- **Output Current:** Up to 250mA  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Dropout Voltage:** 300mV (typical at 250mA)  
- **Quiescent Current:** 80µA (typical)  
- **Line Regulation:** 0.05%/V (typical)  
- **Load Regulation:** 0.1%/mA (typical)  
- **Package:** 8-pin SOIC (MM)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
- The LM2788MM-1.5 is a low-dropout (LDO) voltage regulator designed for battery-powered applications.  
- It provides a stable 1.5V output with low noise and high efficiency.  
- The device includes internal current limiting and thermal shutdown protection.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Extends battery life in portable applications.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limit Protection:** Safeguards against excessive load currents.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  

This information is strictly based on the manufacturer's datasheet for the LM2788MM-1.5.
