描述 Description

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

\t?

\tThe 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.

\t?

\tThe AZ1117E is available in 1.2V, 1.5V, 1.8V, 2.5V, 3.3V and 5.0V?fixed output voltage versions and ADJ output voltage version. The?fixed versions integrate the adjust resistors.

\t?

\tThe AZ1117E is available in the industry-standard SOT-223 package.
