Four LM2940IMP15/NOPB regulators in a SOT2234 package. These are fixed 15V low dropout regulators with lead construction, suitable for compact power designs that require a stable 15V supply. The NOPB suffix indicates no lead (Pb), aligning with RoHS and modern manufacturing standards. Key benefits Fixed 15V output: simplifies design by eliminating external resistor networks and trimming steps. Low dropout performance: allows regulation from rails that are only slightly above the desired 15V, improving efficiency in many applications. Robust current capability: suitable for up to the regulator's rated current with appropriate heat sinking, making it practical for mid power applications. Builtin protection: includes essential safety features to guard your design against overcurrent and overheating. Compact SOT2234 package: small footprint ideal for spaceconstrained PCB layouts. Lead and RoHS compliant: NOPB marking confirms Pb construction for easier integration into modern assemblies. Readytouse quantity: includes 4 pieces per for quick prototyping and production runs. Key attributes Functionality: fixed 15V low dropout regulator (LDO) in a fourlead SOT223 package. Model: LM2940IMP15/NOPB. Package: SOT2234, surfacemount with a metal tab suitable for heat dissipation. Material: plastic SOT223 housing; lead (NOPB). Performance: fixed 15V output with typical LDO characteristics suitable for regulated electronics power. Compatibility: suitable for applications that require a stable 15V supply from higher rails, commonly used in automotive and industrial electronics. Notes: For proper operation, external input and output capacitors per the datasheet are recommended to ensure stability and transient response. Typical applications Automotive 12V systems: provide a stable 15V rail for sensors, instrumentation, or auxiliary circuits from the vehicle power supply. Industrial control boards: supply a consistent 15V reference and power rail for embedded controllers and analog circuitry. Embedded development and prototyping: create a reliable 15V supply on compact PCBs for test rigs or portable electronics requiring fixed 15V regulation. Usage considerations External capacitors: ensure appropriate input and output capacitors are added as specified in the datasheet to maintain stability and transient performance. Thermal management: when delivering higher loads, attach to an adequately sized heatsink or copper plane to manage dissipation in the SOT2234 package. This description remains aligned with the product's model LM2940IMP15/NOPB, its SOT2234 form factor, the lead NOPB designation, and the fact that four pieces are included per . It highlights functionality, compatibility, size, material, performance, and practical use cases without altering the stated specifications.
