Description and Introduction

Dual Micropower Low-Dropout Voltage Regulator The LP2956AIN is a low-dropout voltage regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on factual information:  

### **Specifications:**  
- **Output Voltage Options:** Fixed (3.3V, 5V) or Adjustable (1.24V to 29V)  
- **Output Current:** 250mA (guaranteed)  
- **Dropout Voltage:** 380mV (typical at 250mA)  
- **Input Voltage Range:** Up to 30V  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.04%/mA (typical)  
- **Quiescent Current:** 1.1mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin DIP (PDIP)  

### **Descriptions:**  
- The LP2956AIN is a low-dropout (LDO) voltage regulator designed for applications requiring stable power with minimal input-output differential.  
- It includes built-in protection features such as current limiting and thermal shutdown.  
- Suitable for battery-powered systems, industrial controls, and automotive applications.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation with small input-output differentials.  
- **Low Quiescent Current:** Reduces power consumption in standby modes.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limiting:** Protects against short circuits and overloads.  
- **Adjustable Output (for adjustable version):** Allows flexibility in setting the desired output voltage.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

This information is based on the manufacturer's datasheet for the LP2956AIN.
