Description and Introduction

LM2750 Low Noise Switched Capacitor Boost Regulator The LM2750SD-5.0 is a charge pump DC-DC converter manufactured by National Semiconductor (NS).  

**Specifications:**  
- **Output Voltage:** 5.0V (fixed)  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Current:** Up to 100mA  
- **Efficiency:** Up to 90%  
- **Switching Frequency:** 1.6MHz (typical)  
- **Package:** 10-pin LLP (3mm x 3mm)  
- **Operating Temperature Range:** -40°C to +85°C  

**Descriptions & Features:**  
- **Charge Pump Architecture:** Doubles input voltage to generate a regulated 5V output.  
- **Low Noise:** Uses a constant-frequency switching scheme to minimize output ripple.  
- **No Inductors Required:** Simplifies PCB design and reduces component count.  
- **Low Shutdown Current:** Typically 0.1µA when disabled.  
- **Soft-Start Feature:** Reduces inrush current during startup.  
- **Thermal Shutdown Protection:** Prevents damage from excessive heat.  
- **Applications:** Used in portable devices, white LED drivers, and low-power systems requiring a regulated 5V supply.  

This information is based solely on the manufacturer's datasheet.
