| $1$/2*,& 7(&+ General Description TM AAT1117 1 Amp Linear Regulator Features * * * * * * Guaranteed 1.2V max Dropout at max current Adjustable or Factory programmed output voltages Excellent performance over line, load Current limit protection Over-Temperature protection SOT-223, TO-252 (DPAK) and TO-220 packages The AAT1117 is a Positive Linear Regulator designed to deliver 1 amp. It features adjustable or fixed output voltages and excellent performance over line and load variations. The device is able to protect itself and the load from short circuit conditions with integrated current limiting circuitry. Thermal shutdown is activated to prevent damage under extreme conditions. The AAT1117 is available in surface mount SOT223 or TO-252 (DPAK), and through-hole TO-220 packages.
