Description and Introduction

Voltage Regulator The TLE4470 is a voltage regulator manufactured by Infineon Technologies. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Input Voltage Range:** 5.5 V to 45 V  
- **Output Voltage:** 5 V (fixed)  
- **Output Current:** Up to 400 mA  
- **Dropout Voltage:** Typically 0.5 V at 400 mA  
- **Accuracy:** ±2% (over line, load, and temperature)  
- **Quiescent Current:** Typically 50 µA (in OFF mode: 1 µA)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package Options:** PG-TO263-5-11 (D2PAK), PG-TO252-5-1 (DPAK)  

### **Descriptions:**  
- The TLE4470 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.  
- The device includes protection features such as overtemperature shutdown, reverse polarity protection, and short-circuit protection.  
- It is suitable for use in harsh environments due to its wide operating temperature range.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with low input voltages.  
- **Low Quiescent Current:** Reduces power consumption in standby mode.  
- **Wide Input Voltage Range:** Supports operation in automotive and industrial systems.  
- **Protection Functions:**  
  - Overtemperature shutdown  
  - Short-circuit protection  
  - Reverse polarity protection  
- **AEC-Q100 Qualified:** Meets automotive reliability standards.  
- **Adjustable Reset Threshold:** Allows configuration for different system requirements.  

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