external Power MOSFET multiplied by the output

current. Consequently the output current can be

as high as the POWER MOSFET can provide

(also using an adeguate heatsink).

very low drop voltage operation,the LPR30

requires an external gate drive supply to provide

the control voltage needed to drive the gate of the

external POWER MOSFET.

The regulator output is constant-current limited

when the controller detects 50mV across an

external sense resistor.

It has an internal high precision (

± 2%) Voltage

Reference at 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

an

external pin (N.4) that is able to supply more than

20mA as load current. The LPR30 is available in

8 pin plastic DIP and in SO-8 for SMD. In both

package versions it is able to operate from 0
