- **Input Voltage Range**: 3.5V to 20V  
- **Line Regulation**: 0.02%/V (typical)  
- **Load Regulation**: 0.04% (typical)  
- **Quiescent Current**: 1mA (typical)  
- **Shutdown Current**: 10µA (typical)  
- **Operating Temperature Range**: -40°C to +125°C  
- **Package Options**: TO-220, DD-Pak, SOT-223  

### **Descriptions**:
- The LT1521-3 is a high-performance LDO regulator designed for applications requiring stable, low-noise power.  
- It features low dropout voltage, making it suitable for battery-powered systems.  
- The device includes thermal shutdown and current limit protection.  

### **Features**:
- **Low Dropout Voltage**: 300mV typical at full load.  
- **Low Quiescent Current**: 1mA typical.  
- **Thermal Shutdown Protection**: Prevents overheating.  
- **Current Limit Protection**: Safeguards against overloads.  
- **Stable with Low-ESR Capacitors**: Works with ceramic or tantalum capacitors.  
- **Wide Input Voltage Range**: Supports up to 20V input.
