Description and Introduction

3A Low Dropout Positive Regulators The LM1085IT-12 is a low dropout positive voltage regulator manufactured by National Semiconductor (NSC). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 12V (fixed)
- **Output Current:** 3A
- **Dropout Voltage:** 1.5V (typical at full load)
- **Input Voltage Range:** Up to 29V
- **Line Regulation:** 0.015% (typical)
- **Load Regulation:** 0.1% (typical)
- **Operating Junction Temperature:** -40°C to +125°C
- **Package:** TO-220 (5-pin)

### **Descriptions:**
