Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1129IT-5 is a low dropout (LDO) linear regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** 700mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** Up to 20V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 800µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220 (5-lead)  

### **Descriptions:**  
- The LT1129IT-5 is a high-performance LDO regulator designed for applications requiring stable and precise voltage regulation.  
- It features low dropout voltage, making it suitable for battery-powered and low-input-voltage applications.  
- The device includes thermal shutdown and current limit protection for enhanced reliability.  

### **Features:**  
- Low dropout voltage (300mV typical at full load)  
- Low quiescent current (800µA typical)  
- High output accuracy (±2% over line, load, and temperature)  
- Thermal shutdown and current limit protection  
- Stable with low-ESR output capacitors (≥10µF)  
- Fast transient response  

This information is based on the manufacturer's datasheet for the LT1129IT-5.
