A Product Line of Diodes Incorporated AZ1117E 1.0A LOW DROPOUT LINEAR REGULATOR Description Pin Assignments NEW PRODUCT 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. (Top View) 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 1.2V, 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. VOUT 3 INPUT 2 OUTPUT 1 ADJ/GND SOT-223 Features The AZ1117E is available in the industry-standard SOT-223 package.

Note 4) Note 4: The AZ1117E is compatible with Low ESR ceramic capacitor. A minimum of 1.0μF input and output capacitors are required. The ESR of the output capacitors must be less than 1.5Ω. Close to the OUTPUT pin, it is not recommended to use a capacitor smaller than 0.68μF in parallel with output capacitor. When the output capacitor parallels 0.1µF capacitor, the 0.1µF capacitor must be away from the OUTPUT pin, the distance is no less than 5mm.
