A8586KLJTR-T Description

The A8586KLJTR-T is a high-frequency step-down switching regulator with an integrated high-side power MOSFET. It provides up to 3.5 A output current. The A8586KLJTR-T can achieve fast transient response using current-mode control and simple external compensation. The wide input range of 3.8 to 36 V makes the A8586KLJTR-T suitable for a wide range of step-down applications, including those in an automotive input environment. Battery-driven applications benefit from the low 30 μA operational quiescent current.
