Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1129IS8#PBF is a low dropout (LDO) linear regulator manufactured by **Linear Technology** (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** Fixed 5V or adjustable (depending on variant).  
- **Output Current:** 700mA.  
- **Dropout Voltage:** 300mV typical at full load.  
- **Input Voltage Range:** Up to 30V.  
- **Quiescent Current:** 1mA typical.  
- **Line Regulation:** 0.02% typical.  
- **Load Regulation:** 0.05% typical.  
- **Operating Temperature Range:** -40°C to +125°C.  
- **Package:** 8-Lead SOIC.  

### **Descriptions:**  
- The LT1129 is a high-performance LDO regulator with very low dropout voltage and excellent line/load regulation.  
- It features low noise and high PSRR (Power Supply Rejection Ratio), making it suitable for noise-sensitive applications.  
- Includes built-in protection features such as current limiting and thermal shutdown.  

### **Features:**  
- Low dropout voltage (300mV at full load).  
- Low quiescent current.  
- High output accuracy (±2%).  
- Stable with low-ESR capacitors.  
- Thermal shutdown and current limit protection.  
- Available in fixed and adjustable output versions.  

The LT1129IS8#PBF is commonly used in industrial, automotive, and precision analog applications.
