A8582/83 devices use external compensation to accommodate a wide range of power components and optimise 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 2A (A8582) or 3.5 A (A8583).
Protection features include input undervoltage lockout protection, cycle-by-cycle overcurrent protection, hiccup mode short-circuit protection, overvoltage protection and thermal shutdown. In addition, the A8583 provides unique missing-diode protection, open-circuit, adjacent pin short-circuit, and short-to-ground protection at every pin to satisfy the most demanding applications.
These new devices are targeted at the automotive, telecommunications and networking markets.
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% matt tin-plated lead frames.
