Description and Introduction

Offline Switching Regulator The LT1105CN is a component manufactured by **LINEAR** (Linear Technology Corporation). Below are the specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** LINEAR (Linear Technology)  
- **Part Number:** LT1105CN  
- **Type:** Switching Regulator (DC-DC Converter)  
- **Package:** 8-Pin PDIP (Plastic Dual Inline Package)  
- **Input Voltage Range:** 3V to 30V  
- **Output Voltage:** Adjustable (via external resistors)  
- **Output Current:** Up to 1A (depending on configuration)  
- **Switching Frequency:** 100kHz (fixed)  
- **Efficiency:** Up to 85%  
- **Operating Temperature Range:** 0°C to 70°C  

### **Descriptions:**  
The LT1105CN is a **step-up (boost), step-down (buck), and inverting DC-DC converter** designed for low-power applications. It integrates a **100kHz fixed-frequency oscillator**, a high-efficiency switching regulator, and necessary control circuitry. It is commonly used in battery-powered systems, portable devices, and other applications requiring efficient power conversion.

### **Features:**  
- **Wide Input Voltage Range (3V to 30V)**  
- **Adjustable Output Voltage**  
- **Low Quiescent Current (2.5mA typical)**  
- **Internal Current Limiting & Thermal Shutdown Protection**  
- **Can Operate in Boost, Buck, or Inverting Configurations**  
- **Requires Minimal External Components**  
- **Suitable for Battery-Powered Applications**  

This information is strictly factual and derived from the manufacturer's datasheet and technical documentation.
