Description and Introduction

Dual Micropower Low-Dropout Voltage Regulator The LP2956IM is a low-dropout voltage regulator manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Output Voltage Options:** Fixed (3.3V, 5V) or Adjustable (1.24V to 29V)  
- **Output Current:** Up to 750mA  
- **Dropout Voltage:** 380mV (typical at 750mA)  
- **Input Voltage Range:** Up to 30V  
- **Line Regulation:** 0.04% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 1.1mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin SOIC (IM)  

### **Descriptions and Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Low Quiescent Current:** Reduces power consumption in standby modes.  
- **Thermal and Overcurrent Protection:** Safeguards against overheating and excessive current.  
- **Adjustable Output:** Allows flexibility in setting the desired output voltage.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  
- **Reverse Battery Protection:** Protects the regulator if the input polarity is reversed.  

This regulator is commonly used in battery-powered applications, industrial systems, and automotive electronics.
