GENERAL DESCRIPTION
The L1117 Series are positive and low drop- out three-terminal voltage regulators with 1A output current capability. The devices are designed for u in low voltage applica- tions that offers lower dropout voltage and faster transient respon.
The devices are fully protected against over current faults, over temperature oper- ation, reverd input polarity, reverd lead inrtion, transient voltage spike …etc. On-Chips trimming the reference voltage to 2% and features the low dropout of maxi- mum 1.45 volts.
The L1117 Series regulators offer fixed and adjustable voltage options available in the popular industry standard SOT-223, TO-220, TO-252 and TO-263 packages.
FEATURES
z Fixed 2.5V, 2.85V, 3.3V, 5V or adjustable output voltage
z Low dropout voltage: 1.2V typical at up to 1A z Low ground current z Fast transient respon z Cu
rrent & thermal limiting z Line regulation: 0.5% typical z Load regulation: 0.5% typical z SOT-223,TO-220,TO-252,TO-263 package
APPLICATIONS
z 2.85V active SCSI terminators z 8-15V to 5V linear regulators
z 5V to 2.5V or 3.3V linear regulators z Low voltage micro-controllers z Battery Chargers
z Motherboard clock supplies
z Post regulator for switching supplies z Micro-controllers
* When considering short circuits to ground, the maximum input-to-output differential voltage shall not be allowed greater than approximate 2~3V at values of supply voltage in excess of 10V, continuous short-circuits can exceed the power dissipation ratings and cau eventual destruction.
