Description and Introduction

5 V Low-Drop Fixed Voltage Regulator The TLE4271 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 42 V  
- **Output Voltage:** 5 V (±2%)  
- **Output Current:** Up to 450 mA  
- **Dropout Voltage:** Typically 500 mV at 450 mA  
- **Quiescent Current:** Typically 40 µA (low-power mode)  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package Options:** PG-TO263-5-1 (D2PAK), PG-TO252-3-11 (DPAK), PG-SOT223-4  

### **Descriptions:**  
- The TLE4271 is a low-dropout (LDO) voltage regulator designed for automotive and industrial applications.  
- It provides a fixed 5 V output with high accuracy and low quiescent current.  
- Includes protection features such as overtemperature shutdown, reverse polarity protection, and short-circuit protection.  
- Suitable for harsh environments due to its wide operating temperature range.  

### **Features:**  
- **Low Dropout Voltage:** Ensures stable operation even with small input-output differentials.  
- **Low Quiescent Current:** Enhances efficiency in standby modes.  
- **Overvoltage Protection:** Safeguards against input voltage spikes.  
- **Reverse Polarity Protection:** Prevents damage from incorrect battery connections.  
- **Short-Circuit Proof:** Withstands output short-circuit conditions.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **AEC-Q100 Qualified:** Meets automotive reliability standards.  

This information is based on Infineon's official datasheet for the TLE4271.
