Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1121AIS8#PBF is a low dropout (LDO) linear regulator manufactured by **Linear Technology** (now part of Analog Devices). Below are its key specifications, descriptions, and features based on factual data:  

### **Specifications:**  
- **Output Voltage:** Adjustable (1.24V to 20V)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** Up to 30V  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Quiescent Current:** 950µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Lead SOIC  

### **Descriptions:**  
- The LT1121 is a **low dropout regulator** designed for applications requiring stable voltage with minimal input-output differential.  
- It features **reverse battery protection**, **current limiting**, and **thermal shutdown** for enhanced reliability.  
- Suitable for **battery-powered systems**, **portable devices**, and **industrial applications**.  

### **Features:**  
- **Low Dropout Voltage:** 300mV at full load  
- **Adjustable Output Voltage** (via external resistors)  
- **Low Quiescent Current:** 950µA (typical)  
- **Reverse Battery Protection**  
- **Current Limit & Thermal Shutdown**  
- **Stable with Low-ESR Capacitors**
