1A Fixed and Adjustable Low Dropout Linear Regulator (LDO)
L1117 Series
SOT-223, TO-252, TO-220,TO-263
GENERAL DESCRIPTION
The L1117 Series are positive and low dropout three-terminal
voltage regulators with 1A output current capability. These devices are designed for use in low
voltage applications that offers lower dropout
voltage and faster transient response. These devices are fully protected against over current faults, over temperature operation, reversed input polarity, reversed lead insertion, transient
voltage spike …etc. On-Chips trimming the reference
voltage to 2% and features the low dropout of maximum 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.
