Description and Introduction

UP TO 5A ULTRA LOW DROP OUPUT LINEAR REGULATOR The part **L4957AD1.8** is a **low-dropout (LDO) voltage regulator** manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Output Voltage:** 1.8V (fixed)  
- **Output Current:** Up to 150 mA  
- **Dropout Voltage:** Typically 160 mV at 100 mA load  
- **Input Voltage Range:** 2.5V to 16V  
- **Line Regulation:** 0.2 mV (typical)  
- **Load Regulation:** 2 mV (typical)  
- **Quiescent Current:** 1.5 mA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** TO-92 (through-hole)  

### **Descriptions:**
- Designed for low-power applications requiring a stable 1.8V supply.  
- Includes **overcurrent protection** and **thermal shutdown** for reliability.  
- Suitable for battery-powered devices, embedded systems, and portable electronics.  

### **Features:**
- **Low dropout voltage** for efficient operation.  
- **Low quiescent current** to minimize power consumption.  
- **Thermal protection** prevents overheating.  
- **Short-circuit protected** for enhanced durability.  
- **No external components required** for basic operation (only input/output capacitors recommended).  

For detailed datasheets, refer to **STMicroelectronics' official documentation**.
