The A5975AD is a AEC-Q100 qualified 2.5A step-down switching regulator with a 3.3V reference voltage and an adjustable output voltage from 1.235V to 35V.
The A5975AD is a step-down monolithic power switching regulator designed for automotive applications. It features a minimum switch current limit of 3.1 A, allowing it to deliver up to 2.5 A DC current to the load. The device operates with an input voltage range from 4 V to 36 V and includes a 3.3 V reference voltage. It utilizes an internal P-channel DMOS transistor to minimize external component size and offers a fixed switching frequency of 500 kHz.
