Description and Introduction

Low Noise Regulator Switched Capacitor Boost Regulator The LM2750LDX-ADJ is a switched capacitor voltage converter manufactured by National Semiconductor (NS). Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Adjustable Output Voltage:** 1.24V to 5.5V (via external resistors)  
- **Output Current:** Up to 100mA  
- **Switching Frequency:** 1.6MHz (typical)  
- **Efficiency:** Up to 90%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin WSON (3mm x 3mm)  

### **Descriptions:**  
- The LM2750LDX-ADJ is a high-efficiency, low-noise switched capacitor DC-DC converter.  
- It provides a regulated adjustable output voltage using an external resistor divider.  
- The device operates in a charge-pump topology, eliminating the need for an inductor.  
- It is designed for low-power applications requiring small PCB footprints.  

### **Features:**  
- **Adjustable Output Voltage** via external resistors.  
- **No Inductor Required** – uses flying capacitors for voltage conversion.  
- **Low Output Ripple** due to high switching frequency.  
- **Low Shutdown Current** (<1µA) for power-saving modes.  
- **Thermal Shutdown Protection** to prevent overheating.  
- **Soft-Start Feature** to minimize inrush current.  

This information is based on the manufacturer's datasheet. For further details, refer to the official documentation.
