Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1121CN8-5 is a low dropout (LDO) voltage regulator manufactured by Linear Technology (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Manufacturer:**  
- **LT (Linear Technology)**  

### **Specifications:**  
- **Output Voltage:** 5V (fixed)  
- **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:** 800µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions:**  
- The LT1121CN8-5 is a low dropout regulator designed for applications requiring stable 5V power with minimal voltage headroom.  
- It includes built-in protection features such as current limiting and thermal shutdown.  
- Suitable for battery-powered and industrial applications due to its wide input voltage range.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation with small input-output differentials.  
- **Low Quiescent Current:** Optimized for battery-powered devices.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Current Limit Protection:** Safeguards against excessive load currents.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.
