Description and Introduction

LOW VOLTAGE TELEPHONE SPEECH CIRCUITS Here is the factual information about part **L3281AB** from the manufacturer **STM (STMicroelectronics)**:

### **Specifications:**
- **Manufacturer:** STMicroelectronics (STM)  
- **Part Number:** L3281AB  
- **Type:** Low-dropout (LDO) voltage regulator  
- **Output Voltage:** Fixed (specific value depends on variant)  
- **Output Current:** Up to 150 mA  
- **Dropout Voltage:** Low dropout (typically around 0.2V at full load)  
- **Input Voltage Range:** Up to 10V (exact range may vary)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23 (or similar small surface-mount package)  
- **Quiescent Current:** Low (typically in the microamp range)  
- **Protection Features:** Overcurrent protection, thermal shutdown  

### **Descriptions:**
- The **L3281AB** is a low-dropout linear voltage regulator designed for low-power applications.  
- It provides a stable output voltage with minimal dropout, making it suitable for battery-powered devices.  
- The regulator is optimized for low quiescent current, enhancing efficiency in portable electronics.  

### **Features:**
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for battery-operated applications.  
- **Fixed Output Voltage:** Available in different voltage options (e.g., 1.8V, 2.5V, 3.3V).  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Overcurrent Protection:** Safeguards the regulator and load.  
- **Compact Package:** SOT-23 or similar for space-constrained designs.  

For exact voltage options and detailed electrical characteristics, refer to the official **STM datasheet** for the **L3281AB**.
