AZ1117E Linear LDO Regulator Diodes Inc. AZ1117E low dropout three-terminal regulator delivers 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. 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 bandgap 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 1.2V, 1.5V, 1.8V, 2.5V, 3.3V, and 5.0V fixed output voltage versions and ADJ output voltage versions. The fixed versions integrate the adjusted resistors. The AZ1117E is available in the industry-standard SOT-223 package.
