$1$/2*,& TM AAT1117 7(&+ 1 Amp Linear Regulator General Description Features 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. • • • • 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 Applications • • • • • Active SCSI Terminators High Efficiency Linear Regulators Post Regulators for Switching Supplies Battery Chargers 5V to 3.3V Linear Regulators Typical Application INPUT OUTPUT IN AAT1117 OUT GND/ADJ 10uF 10uF Advanced Analogic Technologies, Inc. 1250 Oakmead Pkwy, Suite 310, Sunnyvale, CA 94086 (408)524-9684 Fax (408)524-9689 2-1 1117.2000.05.0.92 Preliminary Information The AAT1117 is available in surface mount SOT223 or TO-252 (DPAK), and through-hole TO-220 packages. • • $1$/2*,& TM AAT1117 7(&+ 1 Amp Linear Regulator Absolute Maximum Ratings (TA=25°C unless otherwise noted) Symbol VIN IOUT TJ ΘJA ΘJA ΘJA PD PD PD TLEAD Description Input Voltage DC Output Current Operating Junction Temperature Range Thermal Resistance (SOT-223) Thermal Resistance (TO-252) Thermal Resistance (TO-220) Maximum Power Dissipation (SOT-223) Maximum Power Dissipation (TO-252) Maximum Power Dissipation (SOT-220) Maximum Soldering Temperature (at leads, 10 sec) Max Units 15 PD/(VIN-VO) 0 to 125 150 80 60 V mA °C °C/W °C/W °C/W mW mW mW °C Internally Limited 300 Note: Stresses above those listed in Absolute Maximum Ratings may cause permanent damage to the device.
