LM2672M-ADJ/NOPB. – NATIONAL SEMICONDUCTOR

The Texas Instruments LM2672M-ADJ/NOPB is a monolithic, adjustable step-down switching regulator in a space-saving 6-pin SOT-23-5 package. Unlike its fixed-output counterparts, this device offers output voltage adjustability from 1.23V to 37V, making it highly versatile. This adjustability is achieved through an external resistor divider connected to the ADJ pin, providing precise voltage regulation. The device operates with an input voltage range of 4.5V to 40V, enabling its use in a wide variety of applications. _x000D_

The LM2672M-ADJ/NOPB features a switching frequency of 1.2MHz, allowing for the use of smaller, less expensive output capacitors compared to lower frequency regulators. Its internal 1.23V reference provides stable and accurate voltage regulation. Protection features include short-circuit protection, thermal shutdown, and current limiting. The “NOPB” designation indicates a lead-free, halogen-free package, meeting RoHS compliance requirements. Common use cases include powering microcontrollers, sensors, and other low-power circuits requiring precise and adjustable voltage. Its small size and wide input/output voltage ranges make it ideal for space-constrained designs where precise voltage regulation is critical. The high switching frequency facilitates efficient design with minimal external components.
