Diodes Inc.'s AZ1117E is a low-dropout three-terminal regulator with 1.0 A output current ability, and the dropout voltage is specified at typical 1.1 V at 1.0 A current load, decreasing at lower-load currents.

The AZ1117E has been optimized for low-voltage where transient response and minimum input voltage are critical. It provides current limit and thermal shutdown protection solutions. Its circuit includes a trimmed band gap reference to assure output voltage accuracy to be within ±1%. On-chip thermal shutdown provides protection against a combination of high-current and ambient temperature that would create excessive junction temperature.

The AZ1117E is available in 1.2 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V, and 5.0 V fixed output voltage versions and ADJ output voltage version. The fixed versions integrate the adjust resistors. The AZ1117E is available in the industry-standard SOT-223 package.
