APPLICATIONS INFORMATION

In addition, if the output of the LT6106 is wired to a device

thatwilleffectivelyshortittohighvoltage(suchasthrough

an ESD protection clamp) during a reverse supply condi-

tion, the LT6106’s output should be connected through

a resistor or Schottky diode (Figure 7).

Demo Board

Demo board DC1240 is available for evaluation of the

LT6106.

Response Time

ThephotosintheTypicalPerformanceCharacteristicsshow

the response of the LT6106 to a variety of input conditions

and values of RIN. The photos show that if the output

current is very low or zero and an input transient occurs,

there will be an increased delay before the output voltage

begins changing while internal nodes are being charged.
