Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1121CST-5#TR is a low-dropout (LDO) voltage regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** 5V (fixed)  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** Up to 30V  
- **Quiescent Current:** 1.1mA (typical)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.05%/mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223 (Surface Mount)  

### **Descriptions & Features:**  
- **Low Dropout Voltage:** Ensures efficient regulation even with small input-output differentials.  
- **Low Quiescent Current:** Suitable for battery-powered applications.  
- **Thermal Overload Protection:** Prevents damage due to excessive heat.  
- **Reverse Battery Protection:** Withstands reverse input polarity.  
- **Short-Circuit Protected:** Safeguards against output shorts.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum capacitors.  
- **Wide Input Voltage Range:** Supports high-voltage applications.  

This regulator is commonly used in industrial, automotive, and portable electronics where stable voltage regulation is critical.
