PNP Transistor and NPN Transistor integrated as one in
LBN150B01 can be used as a discrete entity for general purpose
applications or as a part of a circuit to function as a Load Switch.
When it is used as the latter as shown in Example Circuit
Schematic, various input voltage sources can be used as long as
they do not exceed the maximum rating of the device. These
devices are designed to deliver continuous output load current up
to maximum of 150 mA. The use of the NPN as a switch
eliminates the need for higher current required to overcome the
gate charge in the event an N-MOSFET is used. Care must be
taken for higher levels of dissipation while designing for higher
load conditions. These devices provide power on demand and
also consume less space. It mainly helps in optimizing power
usage, thereby conserving battery life in a controlled load system
like portable battery powered applications. (Please see Figure
below for one example of typical application circuit used in
conjunction with a voltage regulator as a part of power
management system).
