• Manufacturer: Linear Technology Corporation

PACKAGE DESCRIPTION
APPLICATIONS INFORMATION
In addition, if the output of the LT6106 is wired to a de-
vice that will effectively short it to high voltage (such as
through an ESD protection clamp) during a reverse sup-
ply condition, 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
The photos in the Typical Performance Characteristics show
the response of the LT6106 to a variety of input conditions
and values of R
rent 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.
