Description and Introduction

300mA Low Dropout Regulators with Micropower Quiescent Current and Shutdown The LT1521 is a low dropout regulator (LDO) manufactured by Linear Technology (now part of Analog Devices). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Output Voltage Options:** Fixed (3.3V, 5V) or adjustable (1.24V to 20V).  
- **Output Current:** 1A (guaranteed).  
- **Dropout Voltage:** 500mV (typical at full load).  
- **Input Voltage Range:** Up to 20V.  
- **Line Regulation:** 0.04% (typical).  
- **Load Regulation:** 0.1% (typical).  
- **Quiescent Current:** 1mA (typical).  
- **Operating Temperature Range:** -40°C to +125°C.  
- **Package Options:** TO-220, DD-Pak, and TO-263 (D2PAK).  

### **Descriptions:**  
- The LT1521 is a high-performance LDO regulator designed for applications requiring low noise, high efficiency, and stable operation.  
- It includes protection features such as thermal shutdown and current limiting.  
- Suitable for battery-powered systems, industrial equipment, and telecommunications.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Noise:** Optimized for noise-sensitive applications.  
- **Adjustable Output:** Allows flexibility in setting the desired voltage (for adjustable versions).  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Current Limit:** Safeguards against excessive load currents.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic or tantalum output capacitors.
