Description and Introduction

1A Low Dropout Regulator The LM2940S-10 is a low-dropout (LDO) voltage regulator manufactured by National Semiconductor (NSC). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:

### **Specifications:**
- **Output Voltage:** 10V (fixed)
- **Output Current:** Up to 1A
- **Dropout Voltage:** Typically 0.5V at full load
- **Input Voltage Range:** Up to 26V
- **Line Regulation:** 0.3% (typical)
- **Load Regulation:** 0.4% (typical)
- **Quiescent Current:** 10mA (typical)
- **Operating Temperature Range:** -40°C to +125°C
- **Package:** TO-263 (D2PAK) surface-mount package

### **Descriptions:**
- The LM2940S-10 is a fixed-output LDO regulator designed to provide a stable 10V output with low dropout voltage.
- It includes built-in protection features such as current limiting, thermal shutdown, and reverse-battery protection.
- Suitable for battery-powered applications and systems requiring stable voltage regulation with minimal power loss.

### **Features:**
- Low dropout voltage (0.5V typical at 1A load)
- High output current capability (1A)
- Internal thermal shutdown protection
- Reverse-battery protection
- Short-circuit and overcurrent protection
- Low quiescent current
- Stable with low-ESR output capacitors

This information is strictly factual based on the manufacturer's datasheet.
