GENERAL DESCRIPTION
The ADP194CB-EVALZ is used to demonstrate the function-
ality of the ADP194 power switch.
Simple device measurements such as VIN to VOUT resistance
(RDS
ON
), ground current, and off state current can be demon-
strated with just a single voltage source, a voltmeter, an ammeter,
and a load resistor.
Full details about the ADP194 regulators are available in the
ADP194 data sheet, which should be consulted when using the
ADP194CB-EVALZ.
