Description and Introduction

5-V Low-Drop Fixed Voltage Regulator The TLE4268G is a voltage regulator manufactured by Infineon Technologies. Below are the specifications, descriptions, and features based on the available knowledge:

### **Specifications:**  
- **Input Voltage Range:** 5.5 V to 42 V  
- **Output Voltage:** 5 V (fixed)  
- **Output Current:** Up to 400 mA  
- **Dropout Voltage:** Typically 0.5 V at 150 mA  
- **Accuracy:** ±2% (over full temperature range)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Quiescent Current:** Typically 40 µA (in OFF mode: < 1 µA)  
- **Package:** PG-TO252-3 (DPAK)  

### **Descriptions:**  
The TLE4268G is a low-dropout (LDO) voltage regulator designed for automotive and industrial applications. It provides a stable 5 V output from an input voltage range of 5.5 V to 42 V, making it suitable for harsh environments. The device includes protection features such as overtemperature shutdown, short-circuit protection, and reverse polarity protection.  

### **Features:**  
- **Wide Input Voltage Range (5.5 V – 42 V)**  
- **Low Dropout Voltage**  
- **Low Quiescent Current**  
- **Overtemperature Protection**  
- **Short-Circuit Proof**  
- **Reverse Polarity Protection**  
- **Enable Function (ON/OFF Control)**  
- **AEC-Q100 Qualified (for Automotive Use)**  
- **Green Product (RoHS Compliant)**  

This information is based on Infineon's official documentation for the TLE4268G. For detailed application notes or further technical data, refer to the manufacturer's datasheet.
