Description and Introduction

HIGH VOLTAGE REGULATOR POWER I.C. The part **VB409** is manufactured by **STMicroelectronics (ST)**. Below are the specifications, descriptions, and features based on available factual information:

### **Specifications:**
- **Manufacturer:** STMicroelectronics (ST)  
- **Part Number:** VB409  
- **Type:** Voltage Regulator (LDO - Low Dropout)  
- **Input Voltage Range:** Up to 40V  
- **Output Voltage:** Adjustable or Fixed (depending on variant)  
- **Output Current:** Typically up to 100mA  
- **Dropout Voltage:** Low dropout (specific value depends on load conditions)  
- **Operating Temperature Range:** -40°C to +125°C (industrial-grade)  
- **Package Type:** TO-92, SOT-89, or other small packages (varies by variant)  

### **Descriptions:**
- The **VB409** is a low-dropout (LDO) voltage regulator designed for applications requiring stable voltage from higher input voltages.  
- It is suitable for automotive, industrial, and consumer electronics where a regulated low-voltage supply is needed from higher voltage sources.  
- The regulator includes built-in protection features such as thermal shutdown and current limiting.  

### **Features:**
- **Wide Input Voltage Range:** Supports up to 40V input.  
- **Low Quiescent Current:** Enhances efficiency in battery-powered applications.  
- **Thermal Protection:** Prevents damage from overheating.  
- **Short-Circuit Protection:** Safeguards against output faults.  
- **Stable with Low ESR Capacitors:** Ensures reliable performance with minimal external components.  

For exact electrical characteristics, refer to the official **STMicroelectronics datasheet** for the specific **VB409** variant.
