Description and Introduction

Ultra-Low Ripple Switched Capacitor Voltage Inverter The LM2780TP is a switched capacitor voltage inverter manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 5.5V  
- **Output Voltage:** -Vin (inverted input voltage)  
- **Output Current:** Up to 30mA  
- **Switching Frequency:** 450kHz (typical)  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
The LM2780TP is a compact, high-efficiency switched capacitor voltage inverter that generates a negative output voltage from a positive input. It requires only two external flying capacitors for operation, making it suitable for space-constrained applications.  

### **Features:**  
- No inductors required  
- Low quiescent current (0.5mA typical)  
- Soft-start feature to limit inrush current  
- Thermal shutdown protection  
- Small footprint due to SOT-23-5 package  

This device is commonly used in applications requiring a simple negative voltage supply, such as biasing op-amps, LCD displays, and sensor circuits.
