Description and Introduction

LOW NOISE LOW DROP VOLTAGE REGULATOR WITH SHUTDOWN FUNCTION The **LK112SM25TR** is a low-dropout (LDO) voltage regulator manufactured by **STMicroelectronics (ST)**. Below are its key specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 12V  
- **Output Voltage:** 2.5V (fixed)  
- **Output Current:** 150mA (maximum)  
- **Dropout Voltage:** 200mV (typical at 150mA load)  
- **Line Regulation:** 0.02%/V (typical)  
- **Load Regulation:** 0.2%/mA (typical)  
- **Quiescent Current:** 30µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5L  

### **Descriptions:**  
- The **LK112SM25TR** is a **low-power LDO regulator** designed for battery-powered and portable applications.  
- It provides a **stable 2.5V output** with low dropout voltage and minimal quiescent current, making it suitable for power-sensitive designs.  
- The device includes **overcurrent and thermal shutdown protection** for enhanced reliability.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Low Quiescent Current:** Ideal for battery-operated devices.  
- **Thermal and Overcurrent Protection:** Safeguards the regulator and connected components.  
- **Stable with Low-ESR Capacitors:** Works reliably with ceramic capacitors (≥1µF).  
- **Miniature SOT-23 Package:** Space-saving for compact PCB designs.  

This information is based on STMicroelectronics' official datasheet for the **LK112SM25TR**.
