Infineon Technologies AG Special Purpose Regulators TLE7368GNUMA1

The TLE7368GNUMA1 is a multifunctional power supply circuit designed for automotive applications, specifically for next-generation microcontroller families. It operates within a wide battery input voltage range of 4.5 V to 45 V and is qualified according to AEC-Q100 standards, making it suitable for automotive powertrain systems. The device features a high-efficiency integrated current mode Buck converter that provides a pre-regulated output of 5.5 V with a peak current capability of 2.5 A. It includes multiple low-dropout (LDO) linear regulators, offering outputs of 5 V (800 mA), 3.3 V or 2.6 V (selectable, 700 mA), and a core supply with adjustable voltages of 1.5 V, 1.2 V, or 1.3 V. The TLE7368 also incorporates features such as undervoltage detection, overcurrent protection, power sequencing, and overtemperature shutdown. Its stand-by mode minimizes current consumption, extending battery life. The device is packaged in a small exposed pad PG-DSO-36, ensuring efficient thermal management.
