Description and Introduction

Series of Adjustable Micropower Voltage Regulators The LP2951J/883 is a voltage regulator manufactured by National Semiconductor (NS). Here are its specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 4V to 30V  
- **Output Voltage Options:** Fixed (3.3V, 5V) or Adjustable (1.24V to 29V)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 380mV (typical at 100mA load)  
- **Line Regulation:** 0.2% (typical)  
- **Load Regulation:** 0.4% (typical)  
- **Quiescent Current:** 75µA (typical)  
- **Operating Temperature Range:** -55°C to +125°C  
- **Package:** TO-99 (8-pin metal can)  

### **Descriptions:**  
- The LP2951J/883 is a low-dropout voltage regulator designed for military and aerospace applications.  
- It is qualified to MIL-PRF-38535 standards, ensuring high reliability.  
- The device features built-in protection against reverse battery, short-circuit, and thermal overload.  

### **Features:**  
- **Low Dropout Voltage:** Suitable for battery-powered applications.  
- **Low Quiescent Current:** Enhances efficiency in standby modes.  
- **Error Flag Output:** Warns of output voltage drop (e.g., due to low input voltage).  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  

This information is based on the manufacturer's datasheet for the LP2951J/883.
