Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1121ACS8-3.3 is a low dropout (LDO) voltage regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** 4V to 30V  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Quiescent Current:** 1.5mA (typical)  
- **Package:** 8-Lead SOIC (SO-8)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Reverse battery protection, current limiting, thermal shutdown  

### **Descriptions and Features:**  
- Designed for low dropout and high-efficiency regulation.  
- Stable with low-ESR capacitors (≥1µF).  
- Reverse battery protection prevents damage if input polarity is reversed.  
- Low quiescent current makes it suitable for battery-powered applications.  
- Thermal shutdown prevents overheating.  
- Suitable for industrial, automotive, and portable electronics.  

The LT1121ACS8-3.3 provides reliable voltage regulation in a compact SO-8 package.
