Description and Introduction

Low Noise Step-Down Switching Regulator The LT1777CS#PBF is a high efficiency, low noise step-down switching regulator manufactured by Linear Technology (now part of Analog Devices).  

### **Specifications:**  
- **Input Voltage Range:** 3.5V to 25V  
- **Output Voltage Range:** Adjustable from 1.23V to 20V  
- **Output Current:** Up to 1.5A  
- **Switching Frequency:** 200kHz  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** 0°C to 70°C  
- **Package:** 16-Lead SOIC  

### **Descriptions:**  
- The LT1777 is a current-mode PWM buck (step-down) regulator.  
- It features low dropout operation, allowing the output to remain in regulation even when the input voltage approaches the output voltage.  
- The device includes a soft-start function to limit inrush current during startup.  

### **Features:**  
- **Low Noise Operation:** Minimizes output ripple.  
- **Current Mode Control:** Provides fast transient response.  
- **Low Dropout Operation:** Maintains regulation with small input-output differentials.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Enhances reliability.  

This regulator is commonly used in battery-powered systems, industrial applications, and distributed power supplies.
