Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The TPS7B4253QDDARQ1 device is designed for automotive applications where 45V load drops are an issue. The device can be used as a tracking low dropout voltage (LDO) regulator or voltage tracker to create a closed power loop for off-board sensors from the on-board mains supply. The output of the device is precisely regulated by the reference voltage on the ADJ pin.
