as high as the POWER MOSFET can provide

of the LPR30 range from 5V to 30V. For
very low drop voltage operation,the LPR30
requires an external gate drive supply to provide
the control voltageneeded to drive the gate of the
externalPOWER MOSFET.
The regulator output is constant-current limited
when the controller detects 50mV across an
externalsense resistor.
It has an internal high precision (
±
2%) Voltage
Referenceat 2.5V
The output regulated voltage is possible to
program to any voltage from 1V to more than
50V.
Flexible design is achieved by the availability of
