DESCRIPTION
The LPR30 is a very Low Dropout Regulator
Controller in a single IC solution for very high
current low dropout linear voltage regulator. It
uses an external N-CHANNEL POWER MOSFET
as the linear pass element. The LPR30 features a
dropout voltage as low as the RDS(ON) of the
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 adequate 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.
