PART OBSOLETE - USE AZ1117C AZ1117E 1.0A LOW DROPOUT LINEAR REGULATOR Description Pin Assignments The AZ1117E is a low-dropout three-terminal regulator with 1.0A (Top View) output current ability, and the dropout voltage is specified at typical 1.1V at 1.0A current load decreasing at lower load currents. INPUT 3 The AZ1117E is optimized for low voltage where transient response and minimum input voltage are critical. It provides current limit and VOUT 2 OUTPUT thermal shutdown protection solutions. Its circuit includes a trimmed band gap reference to assure output voltage accuracy to be within 1 ADJ/GND 1%. On-chip thermal shutdown provides protection against a combination of high current and ambient temperature that would SOT-223 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. The AZ1117E is available in the industry-standard SOT-223 package.

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