LMN200B02
200 mA LOAD SWITCH FEATURING PRE-BIASED PNP TRANSISTOR AND N-MOSFET
WITH GATE PULL DOWN RESISTOR
Please click here to visit our online spice models database.
General Description
LMN200B02 is best suited for applications where the load needs to
be turned on and off using control circuits like micro-controllers,
comparators etc. particularly at a point of load. It features a
discrete pass transistor with stable VCE(SAT) which does not
depend on the input voltage and can support continuous maximum
current of 200 mA . It also contains a discrete N-MOSFET that can
be used as control. This N-MOSFET also has a built-in pull down
resistor at its gate. The component can be used as a part of a
circuit or as a stand alone discrete device.
