LBN150B01 150 mA LOAD SWITCH FEATURING COMPLEMENTARY BIPOLAR TRANSISTORS Please click here to visit our online spice models database. NEW PRODUCT 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 Vce_sat which does not depend on the input voltage and can support maximum continuous current of 150 mA up to 125 °C (see fig. 1). 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 standalone discrete devices. 6 5 4 1 2 3 Features • • • • Epitaxial Planar Die Construction Ideally Suited for Automated Assembly Processes Lead Free By Design/ROHS Compliant (Note 1) "Green" Device (Note 2) SOT-26 CQ1 EQ2 CQ2 6 5 4 Mechanical Data • • • • • • • • Case: SOT-26 Case Material: Molded Plastic.

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).
