Description and Introduction

Low Noise Regulated Switched Capacitor Voltage Inverter in micro SMD The LM2787TPX is a switched capacitor voltage inverter manufactured by National Semiconductor (now part of Texas Instruments). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** National Semiconductor  
- **Type:** Switched Capacitor Voltage Inverter  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** -Vin (Inverts 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-23-6  

### **Descriptions:**  
The LM2787TPX is a charge pump voltage inverter that generates a negative output voltage from a positive input supply. It uses a switched capacitor architecture, eliminating the need for an inductor. The device is designed for low-power applications where space and efficiency are critical.  

### **Features:**  
- No Inductors Required  
- Low Quiescent Current: 100µA (Typical)  
- High Efficiency (Up to 96%)  
- Fixed Inverting Output (-Vin)  
- Low Output Impedance  
- Thermal Shutdown Protection  
- Small SOT-23-6 Package  

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

Description and Introduction

Low Noise Regulated Switched Capacitor Voltage Inverter in micro SMD The LM2787TPX is a switched-capacitor voltage inverter manufactured by Texas Instruments (NS).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 5.5V  
- **Output Voltage:** -Vin (inverted input voltage)  
- **Output Current:** Up to 30mA  
- **Switching Frequency:** 350kHz (typical)  
- **Efficiency:** Up to 96%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
The LM2787TPX is a charge pump voltage inverter that generates a negative output voltage from a positive input supply. It does not require inductors, making it suitable for space-constrained applications.  

### **Features:**  
- No inductors required  
- Low quiescent current (120µA typical)  
- Automatic shutdown in undervoltage lockout (UVLO)  
- Soft-start feature to reduce inrush current  
- Short-circuit and thermal protection  

This information is based on the manufacturer's datasheet.
