The A8582/83 devices utilize external compensation to accommodate a wide range of power components and optimize transient response without sacrificing stability. Both devices regulate input voltages from 4.7 V to 36 V down to output voltages as low as 0.8 V, and are able to supply load current of at least 2 A (A8582) or 3.5 A (A8583).
Protection features include VIN under voltage lockout (UVLO), cycle-by-cycle over current protection (OCP), hiccup mode short-circuit protection (HIC), over voltage protection (OVP), and thermal shutdown (TSD). In addition, the A8583 provides unique missing diode (D1) protection, open-circuit, adjacent pin short-circuit, and short-to-ground protection at every pin to satisfy the most demanding applications.
The A8582/A8583 devices are available in a 16-pin TSSOP package with exposed pad for enhanced thermal dissipation and are lead (PB) free with 100% matte tin plated lead frames.
