Description and Introduction

Dual Low Dropout Voltage Regulator Stand-by output 190 mA; 5 V ± 2% The TLE4473GV55-2 is a voltage regulator manufactured by Infineon. Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Output Voltage:** 5.0 V  
- **Output Current:** 400 mA  
- **Input Voltage Range:** 5.5 V to 45 V  
- **Dropout Voltage:** Typically 0.5 V at 400 mA  
- **Quiescent Current:** Typically 40 µA  
- **Operating Temperature Range:** -40°C to +150°C  
- **Package:** PG-TO263-5-11 (DPAK-5)  

### **Descriptions:**  
- The TLE4473GV55-2 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.  

### **Features:**  
- **Low Dropout Voltage:** Ensures efficient operation even with small input-output differentials.  
- **Wide Input Voltage Range:** Supports operation from 5.5 V up to 45 V.  
- **Low Quiescent Current:** Reduces power consumption in standby mode.  
- **High Accuracy:** Tight output voltage tolerance (±2%).  
- **Protection Features:**  
  - Overtemperature shutdown  
  - Reverse polarity protection  
  - Short-circuit protection  
  - Overvoltage protection  
- **Automotive Qualified:** AEC-Q100 compliant for reliable performance in harsh environments.  

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

Application Scenarios & Design Considerations

Dual Low Dropout Voltage Regulator Stand-by output 190 mA; 5 V ± 2%

Alternative Part Number

  • NCV4275CDT50RKG --: Dual low-dropout linear regulator with 5V outputs and similar current capability, suitable replacement for automotive power supply applications.
  • LP2953IMX-5.0 --: Dual 5V low-dropout regulator with comparable output current and voltage accuracy, pin-compatible in many designs.
  • TLE4275G --: Single 5V low-dropout regulator from a different Infineon series with similar electrical characteristics, usable where dual outputs are not strictly required.
  • TLE4471G --: Same TLE447x family of automotive dual low-dropout voltage regulators with comparable current capability and protection features; verify the fixed output voltage option matches the 5 V rail requirement.
  • NCV4275A --: Automotive 5 V LDO regulator with comparable dropout, current rating and protection circuitry from an alternate vendor, offering a cross-manufacturer second source.
  • TLE4473G V55 --: Same TLE4473G dual low-dropout regulator family with 5.5V output, functionally equivalent to the original with only package/ordering variant differences.
  • TLE4476D --: Infineon dual LDO regulator in the same automotive-grade family, offering comparable current capability and voltage regulation for similar applications.
