TLE42744DV50 Product Overview

The Infineon TLE42744DV50 is a fixed 5V output low-dropout (LDO) linear regulator with a maximum output current of 400mA. Engineered for the demanding conditions of automotive applications, this device delivers high precision and multiple protection features, ensuring the stability and reliability of in-vehicle electronics under complex operating conditions.

TLE42744DV50 Key Features

The TLE42744DV50's core strengths lie in its comprehensive protection, high performance, and exceptional reliability.

Comprehensive Protection: The chip integrates overload protection, short-circuit protection, reverse polarity protection, over-temperature protection, and over-voltage protection (OVP), effectively preventing device or system damage from various anomalies.

High-Performance Parameters:

Wide Input Voltage Range: 5.5V to 40V, accommodating fluctuations in automotive power systems such as load dump events.

Low Dropout Voltage: Typically just 500mV @ 250mA (alternative data indicates 250mV @ 250mA), meaning minimal input-output voltage difference during high-current output, resulting in higher efficiency and reduced heat generation.

High-Precision Output: Output voltage accuracy of ±2% delivers stable, reliable power to loads.

Low Quiescent Current: Standby current of 220μA contributes to reduced overall system power consumption.

High Power Supply Rejection Ratio (PSRR): 60dB @ 100Hz effectively suppresses input power supply noise, providing clean output voltage.

High-reliability design:

Wide operating temperature range: -40°C to +150°C, meeting automotive electronics' demands for extreme environments.

Automotive compliance: Chip conforms to AEC-Q100 standards with low ESR characteristics, specifically engineered for automotive applications.

Environmentally friendly: Lead-free and RoHS compliant.
