NIKO-SEM 3A Adjustable Low Dropout L1085
Linear Regulator (LDO) TO-252,263,220
GENERAL DESCRIPTION FEATURES
The L1085 is a positive and low dropout Very easy to use, it requires only two
three-terminal voltage regulator with 3A out- external resistors to set the output voltage
put current capability. This device is design- Low dropout voltage:
ed for use in low voltage applications that 1.3V typical at up to 3A
offers lower dropout voltage and faster tran- Low ground current
sient response. Fast transient response
This device is fully protected against over Current & thermal limiting
current faults, over temperature operation, Line regulation: 0.5% typical
reversed input polarity, reversed lead insert- Load regulation: 0.5% typical
