Description and Introduction

Low Noise Regulated Switched Capacitor Voltage Inverter in micro SMD The LM2787BP is a charge pump voltage inverter manufactured by National Semiconductor (NS).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** -Vin (inverted input voltage)  
- **Output Current:** Up to 50mA  
- **Switching Frequency:** 350kHz (typical)  
- **Efficiency:** Up to 96%  
- **Low Quiescent Current:** 0.6mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin SOIC  

### **Descriptions:**  
- The LM2787BP is a switched-capacitor voltage inverter that generates a negative output voltage from a positive input.  
- It does not require inductors, making it suitable for space-constrained applications.  
- The device includes an internal oscillator and requires only two external capacitors for operation.  

### **Features:**  
- **No Inductors Required** – Uses only flying capacitors.  
- **Low Output Impedance** – Ensures stable performance under varying loads.  
- **Low Noise Operation** – Minimizes interference in sensitive circuits.  
- **Thermal Shutdown Protection** – Prevents damage from overheating.  
- **Short-Circuit Protection** – Enhances reliability.  

This information is based on the manufacturer's datasheet and technical documentation.
