... R . (See Applications Information section for more DS(ON) details.) V (Pins 1,8): The output pins of the LTC1477 must OUT always be tied together. The output is protected against accidental short circuits to ground by a current limit circuit which protects the system power supply and load against damage. A second level of protection is provided by thermal shutdown circuitry which limits the die tempera- ture to 130 C ...

... LTC1477. The switch is protected against accidental short circuits with a current limit circuit which limits the output current to typically 2A when the output is shorted to ground. The LTC1477 also has thermal shut- down set at approximately 130 C which limits the power dissipation to safe levels. ...

... Supply Bypassing For best results, bypass the supply input pins with a single 1.0 F capacitor as close as possible to the LTC1477. Sometimes, much larger capacitors are already available at the output of the power supply. In this case still good practice to use a 0.1 F capacitor as close as possible ...
