Description and Introduction

Low-Drop Voltage Regulator The TLE4276DV50 is a low-dropout voltage regulator manufactured by Infineon. Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Output Voltage:** 5.0 V (±2% accuracy)  
- **Input Voltage Range:** 5.5 V to 45 V  
- **Dropout Voltage:** Typically 0.5 V at 400 mA  
- **Output Current:** Up to 400 mA  
- **Quiescent Current:** Typically 60 µA (low-power mode)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** TO-252-5 (DPAK)  

### **Descriptions:**  
- Designed for automotive and industrial applications.  
- Includes overtemperature, short-circuit, and reverse polarity protection.  
- Features a watchdog and reset functionality for microcontroller supervision.  

### **Features:**  
- **Low Dropout Voltage:** Ensures stable output even with low input voltage.  
- **Low Quiescent Current:** Enhances efficiency in standby mode.  
- **High Accuracy:** Tight output voltage tolerance (±2%).  
- **Protection Mechanisms:** Overcurrent, overtemperature, and reverse polarity protection.  
- **Watchdog Timer:** Monitors system integrity for automotive applications.  
- **Adjustable Reset Threshold:** Configurable reset delay for microcontroller supervision.  

This regulator is suitable for power supply applications requiring reliability and robustness in harsh environments.
