Description and Introduction

LOW NOISE LOW DROP VOLTAGE REGULATOR WITH SHUTDOWN FUNCTION The **LK112M25TR** 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:** 2.5V (fixed)  
- **Output Current:** Up to 150mA  
- **Dropout Voltage:** Typically 160mV at 100mA load  
- **Input Voltage Range:** 2.7V to 12V  
- **Line Regulation:** 0.05% (typical)  
- **Load Regulation:** 0.1% (typical)  
- **Quiescent Current:** 50µA (typical)  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** SOT-23-5L  

### **Descriptions:**  
- The **LK112M25TR** is a **low-power LDO regulator** designed for battery-powered and portable applications.  
- It provides a stable **2.5V output** with low noise and high PSRR (Power Supply Rejection Ratio).  
- Includes **overcurrent and thermal protection** for enhanced reliability.  
- Suitable for **consumer electronics, IoT devices, and embedded systems**.  

### **Features:**  
- **Low dropout voltage** (160mV typical at 100mA)  
- **Ultra-low quiescent current** (50µA typical)  
- **High PSRR** (60dB at 1kHz)  
- **Thermal shutdown and current limit protection**  
- **Stable with low-ESR ceramic capacitors** (≥1µF)  
- **Small SOT-23-5L package** for space-constrained designs  

This information is sourced from **STMicroelectronics' official datasheet** for the LK112M25TR.
