Infineon Technologies AG Voltage Regulators - Linear TLE7270-2D

The TLE7270-2D is a 5-V low dropout voltage regulator designed for automotive applications, capable of regulating input voltages up to 42 V to a precise output of 5 V ±2%. It supports output currents up to 300 mA and features an ultra-low quiescent current of 20 µA, making it suitable for applications that are continuously connected to the battery. The device includes integrated reset circuitry for power-on timing and output voltage monitoring, enhancing its utility as a microcontroller supply. Protection features include output current limitation and overtemperature shutdown, ensuring reliability in harsh environments. The TLE7270-2D is compatible with ceramic output capacitors as low as 470 nF, promoting stable operation. It is AEC qualified and RoHS compliant, affirming its suitability for automotive and other demanding applications. However, for applications requiring extremely low noise levels, alternative products from the TLE 42XX or TLE 44XX series may be more appropriate.
