LPR30 LOW DROP VOLTAGE REGULATOR DRIVE FOR EXTERNAL N-CHANNEL POWER MOSFET

® LPR30 LOW DROP VOLTAGE REGULATOR DRIVE FOR EXTERNAL N-CHANNEL POWER MOSFET s s s s s s s s s VERY LOW DROPOUT POWER MOSFET DRIVER HIGH PRECISION Vref = 2.5V (± 2%) VERY LOW CURRENT DRAIN (TYP. 2mA) REFERENCE OUTPUT CURRENT UP TO 20mA OPERATING SUPPLY VOLTAGE FROM 5V TO 30V MAXIMUM INPUT VOLTAGE ON-GATE PIN (N. 8) UP TO 60V INTERNAL CURRENT LIMIT OPERATIONAL AMPLIFIER OFFSET TRIMMED AT 50mV ± 10mV NO CAPACITOR IS NEEDED FOR STABILITY OF REFERENCE OUTPUT TEMPERATURE RANGE 0 oC TO 70 oC .

LPR30 Features

* a dropout voltage as low as the RDS(on) of the May 2000 1/10 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 V CC of the LPR30 range from 5V to 30V. For very low dro
