Description and Introduction

Micropower Low Dropout Regulators with Shutdown The LT1121IST-5#PBF is a low dropout (LDO) voltage regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Output Voltage:** Fixed 5V  
- **Output Current:** 150mA  
- **Dropout Voltage:** 300mV (typical at full load)  
- **Input Voltage Range:** Up to 30V  
- **Line Regulation:** 0.02% (typical)  
- **Load Regulation:** 0.05% (typical)  
- **Quiescent Current:** 950μA (typical)  
- **Package:** SOT-223 (Surface Mount)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Protection Features:** Reverse battery protection, current limiting, thermal shutdown  

### **Descriptions:**  
The LT1121IST-5#PBF is a high-performance LDO regulator designed for applications requiring stable, low-noise power with minimal dropout voltage. It is optimized for battery-powered systems and can handle input voltages up to 30V while maintaining tight regulation.  

### **Features:**  
- Low dropout voltage (300mV typical at full load)  
- Low quiescent current (950μA typical)  
- High output accuracy (±2%)  
- Reverse battery protection  
- Thermal shutdown and current limit protection  
- Stable with low-ESR capacitors  
- Wide input voltage range (up to 30V)  

This regulator is suitable for portable electronics, automotive systems, and industrial applications where stable power is critical.
