Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1121IS8-3.3 is a low dropout (LDO) voltage regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Manufacturer Specifications:**  
- **Output Voltage:** 3.3V (fixed)  
- **Input Voltage Range:** Up to 30V  
- **Dropout Voltage:** 300mV (typical at 150mA load)  
- **Output Current:** 150mA  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.04%/mA (typical)  
- **Quiescent Current:** 1mA (typical)  
- **Package:** 8-Lead SOIC (SO-8)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Protection Features:** Reverse battery protection, current limiting, thermal shutdown  

### **Descriptions and Features:**  
- **Low Dropout:** Operates with very small input-output differential voltage.  
- **Wide Input Range:** Supports up to 30V input.  
- **Low Quiescent Current:** Efficient for battery-powered applications.  
- **Stable with Low-ESR Capacitors:** Works with ceramic or tantalum output capacitors.  
- **Reverse Battery Protection:** Safeguards against incorrect polarity connection.  
- **Current Limiting & Thermal Shutdown:** Protects against overload and overheating.  
- **Precision Output:** Tight voltage tolerance (±2% over line, load, and temperature variations).  

This regulator is commonly used in industrial, automotive, and portable electronics requiring stable 3.3V power from higher input voltages.
