Description and Introduction

5-V Low-Drop Fixed Voltage Regulator The TLE4279GM is a voltage regulator manufactured by Infineon Technologies. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 5.5 V to 42 V  
- **Output Voltage:** 5 V (fixed)  
- **Output Current:** Up to 400 mA  
- **Dropout Voltage:** Typically 500 mV at 400 mA  
- **Accuracy:** ±2% (over full temperature range)  
- **Quiescent Current:** Typically 40 µA (in OFF mode: < 1 µA)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** PG-TO252-3 (DPAK)  

### **Descriptions:**  
- The TLE4279GM is a low-dropout (LDO) voltage regulator designed for automotive and industrial applications.  
- It provides a stable 5 V output with high accuracy and low quiescent current.  
- Features reverse polarity protection and overtemperature shutdown.  
- Suitable for harsh environments due to its wide operating temperature range.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with low input voltages.  
- **Reverse Polarity Protection:** Safeguards the device against incorrect battery connections.  
- **Overtemperature Protection:** Prevents damage due to excessive heat.  
- **Low Quiescent Current:** Ideal for battery-powered applications.  
- **Short-Circuit Protection:** Enhances reliability in fault conditions.  
- **AEC-Q100 Qualified:** Meets automotive industry standards.  

This information is based solely on the manufacturer's datasheet and technical documentation.
