Infineon Voltage Regulators TLE42744DV50
Applicable to automotive applications, the TLE42744DV50 is a fixed output voltage regulator from Infineon Technologies' OPTIREGTM line. It has a temperature range of -40 to 150 degrees Celsius and can withstand a maximum input voltage of 40 volts with reliability.
Description
Feature
A semiconductor product from Infineon Technologies' OPTIREGTM series is the TLE42744DV50. This TO-252-3 package contains a surface-mount regulator that is ideal for use in automotive applications.- Now let's explore its particular parameters: It can handle input voltages up to 40 volts and deliver a maximum output current of 400 milliamperes with a fixed 5-volt output, all while keeping a low quiescent current of 220 microamperes.
- Ensuring effective power conversion, its maximum voltage dropout is 0.5 volts at 250 milliamperes. This improves system reliability with protection features like reverse polarity, overcurrent, overtemperature, and short-circuit protection.
- It is the perfect option for automotive electronic applications since it can operate in a broad temperature range of -40 to 150 degrees Celsius and because its high-temperature resistance satisfies automotive-grade standards (AEC-Q100) for durability and dependability.
Choosing External Parts
The TLE42744DV50 voltage regulator's performance can be enhanced by carefully choosing the external parts:
- Use a ceramic capacitor (100 nF ~ 470 nF) to remove high-frequency interferences such as ISO pulses 3 a/b. Putting it close to the PCB's input- pin will help to successfully minimize disruptions.
- Use an aluminium electrolytic capacitor (10 μF ~ 470 μF) for buffering high-energy pulses such as ISO pulse 2a. Placing correctly in relation to the input pin ensures effective buffering.
- While using a diode for overvoltage suppression is not required, it is recommended to provide extra protection against voltage spikes that exceed the regulator's maximum rating. This shields the device from overvoltage situations that would otherwise result in harm.
