Infineon TLE42962GV50HTSA1 5V Low-Dropout Voltage Regulator: Features and Applications
The Infineon TLE42962GV50HTSA1 is a monolithic integrated low-dropout voltage regulator designed to deliver a precise, stable 5V output. As a critical component in modern electronic systems, it ensures reliable power supply even under challenging conditions, making it a preferred choice for automotive, industrial, and consumer applications. This article explores its key features and typical use cases.
Key Features of the TLE42962GV50HTSA1
One of the standout attributes of this LDO regulator is its very low dropout voltage, typically 200 mV at maximum load. This allows it to maintain regulation even when the input voltage is only slightly above the output level, enhancing efficiency and extending battery life in portable devices. The device offers a fixed 5V output with high accuracy (±2%), ensuring stable performance for sensitive circuits like microcontrollers, sensors, and communication modules.
Additionally, the regulator incorporates comprehensive protection mechanisms, including overcurrent limitation, overtemperature shutdown, and reverse polarity protection. These features safeguard both the regulator and the connected load from potential damage in fault conditions. Its low quiescent current in standby mode makes it suitable for power-sensitive applications, while the enable function allows for external control of the output, facilitating power management in complex systems.
The TLE42962GV50HTSA1 is housed in a thermally enhanced PG-TO252-3 package, which provides excellent heat dissipation, crucial for high-current applications up to 250 mA. Its wide input voltage range (5.5V to 42V) and robustness against load dumps and transients make it particularly ideal for automotive environments, where voltage spikes are common.
Applications
Thanks to its rugged design and reliability, this LDO is widely used in automotive electronics, such as infotainment systems, instrument clusters, and engine control units (ECUs). It ensures stable power for critical components despite fluctuations in the vehicle’s electrical system. In industrial settings, it powers PLCs, sensors, and actuators, where consistent voltage is essential for accuracy and safety. Consumer electronics, including set-top boxes and networking equipment, also benefit from its efficiency and compact form factor.
The Infineon TLE42962GV50HTSA1 stands out as a robust, efficient solution for 5V power regulation, combining low dropout, high accuracy, and extensive protection in a durable package. Its versatility across industries underscores its value in ensuring system reliability.
