Description and Introduction

VERY LOW DROP VOLTAGE REGULATOR WITH INHIBIT The **L4931CV12** 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:** 1.2V (fixed)  
- **Input Voltage Range:** Up to 28V  
- **Dropout Voltage:** 0.4V (typical at 100mA load)  
- **Output Current:** Up to 250mA  
- **Quiescent Current:** 1.5mA (typical)  
- **Line Regulation:** 0.3mV (typical)  
- **Load Regulation:** 3mV (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-220 (5-pin)  

### **Descriptions:**  
- The **L4931CV12** is a **low-dropout linear regulator** designed for applications requiring stable and precise **1.2V** output.  
- It includes **short-circuit protection**, **thermal shutdown**, and **reverse polarity protection**, enhancing reliability.  
- Suitable for automotive, industrial, and consumer electronics due to its **wide input voltage range** and **robust design**.  

### **Features:**  
- **Low dropout voltage** (0.4V typical at 100mA)  
- **Very low quiescent current** (1.5mA typical)  
- **High ripple rejection** (60dB at 1kHz)  
- **Internal current and thermal limiting**  
- **Reverse battery protection** (up to -28V)  
- **Compliant with automotive standards** (AEC-Q100 qualified)  

This information is sourced from the **official STMicroelectronics datasheet** for the **L4931CV12**.
