Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1129CT-3.3 is a low dropout (LDO) voltage regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** Up to 20V  
- **Dropout Voltage:** 300mV (typical) at 700mA load  
- **Output Current:** 700mA (maximum)  
- **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 and Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Reverse Battery Protection:** Safeguards against incorrect power connections.  
- **Current Limit Protection:** Prevents damage from excessive load currents.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.  

This regulator is commonly used in battery-powered devices, industrial systems, and precision analog circuits requiring stable voltage regulation.
