Overview
The L5150GJTR is a low dropout linear regulator produced by STMicroelectronics, designed for automotive applications. It features microprocessor control functions including power on reset, low voltage reset, early warning, and on/off control. The regulator maintains high output voltage accuracy of ±2% over a wide temperature range, line, and load variations. It has a typical quiescent current of 55 µA in very low output current mode and drops to 5 µA when not enabled. The device also includes thermal shutdown and short-circuit protection, ensuring reliable operation in various conditions.
