NEW PRODUCT A Product Line of Diodes Incorporated AZ1117E 1.0A LOW DROPOUT LINEAR REGULATOR Description Pin Assignments 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. 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.
