This pin is the positive side of the reference voltage for this device. With this pin it is possible to
Kelvin sense the output voltage at the load.
This pin is the negative side of the reference voltage for the device. Transient response can be
improved by adding a small bypass capacitor from the adjust pin to ground.
This pin is the bottom end of the internal resistor feedback chain for fixed output voltage parts,
and should be connected to ground.
This is the power output of the device, and is electrically connected to the TAB.
be approximately 1% of the output current. For the device to regulate, the voltage at this pin must
be between 1.0V and 1.3V greater than the output voltage (see dropout specifications).
This is the collector input to the power device of the EZ158X. The output load current is supplied
through this pin. For the device to regulate, the voltage on this pin must be between 0.1V and
0.7V greater than the output voltage, depending upon load current (see dropout specifications).
