Description and Introduction

VERY LOW DROP 1.5 A REGULATORS The **L4940D2T85-TR** is a low-dropout (LDO) voltage regulator manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features based on factual data:

### **Specifications:**
- **Output Voltage:** 5V (Fixed)  
- **Output Current:** 100mA  
- **Dropout Voltage:** 0.4V (Typical at 100mA)  
- **Input Voltage Range:** Up to 28V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-223 (Surface Mount)  
- **Line Regulation:** 10mV (Typical)  
- **Load Regulation:** 15mV (Typical)  
- **Quiescent Current:** 1.5mA (Typical)  

### **Descriptions:**
- The **L4940D2T85-TR** is a **low-dropout voltage regulator** designed for applications requiring stable 5V output with minimal power dissipation.  
- It features **thermal shutdown** and **short-circuit protection**, enhancing reliability in harsh conditions.  
- Suitable for **automotive, industrial, and consumer electronics** due to its wide input voltage range.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Thermal Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards the regulator and connected circuitry.  
- **Wide Input Voltage Range:** Supports up to 28V input.  
- **Low Quiescent Current:** Reduces power consumption in standby mode.  
- **SOT-223 Package:** Compact and suitable for space-constrained designs.
