TLE4251GATMA1 Infineon Linear Voltage Regulator | PG-TO263-5-1 | 5V, 400mA

Product Overview

The TLE4251GATMA1 is a high-precision, low-dropout (LDO) linear voltage regulator from Infineon Technologies, designed for automotive and industrial applications. It provides a fixed output voltage of 5V with a maximum output current of 400mA. The device is housed in a PG-TO263-5-1 package, offering excellent thermal performance and reliability. With a dropout voltage as low as 0.25V at 100mA, it ensures efficient operation even under low input voltage conditions. The TLE4251GATMA1 features integrated protection functions including overcurrent protection, overtemperature shutdown, and reverse polarity protection, making it suitable for harsh environments.
