LBN150B01
150 mA LOAD SWITCH FEATURING COMPLEMENTARY BIPOLAR TRANSISTORS
General Description
• LMN150B01 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 PNP pass transistor with stable
V_{ce_sat} which does not depend on the input voltage and
can support maximum continuous current of 150 mA up to
125 °C (see fig. 3). It also contains a discrete NPN that can
be used as a control. The component devices can be used
as a part of a circuit or as stand alone discrete devices.
