LPR30
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).
The VCC 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 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
the Voltage Reference Output through 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 0oC to
70oC.
