GENERAL DESCRIPTION
The L1085 is a positive and low dropout three-terminal
voltage regulator with 3A output current capability. This device is designed for use in low
voltage applications that offers lower dropout
voltage and faster transient response.

This device is 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 1% and features the low dropout of maximum 1.50 volts. The L1085 Series regulators are available in the popular industry standard TO-263 TO-220 and TO-252 packages.
z Very easy to use, it requires only two external resistors to set the output
voltage z Low dropout
voltage: 1.3V typical at up to 3A z Low ground current z Fast transient response z Current & thermal limiting z Line regulation: 0.5% typical z Load regulation: 0.5% typical z TO-263, TO-220 and TO-252 packages
