Quality Control: Learn More
Texas Instruments LP3855EMP-ADJ is an adjustable positive linear voltage regulator designed for applications requiring precise voltage regulation and high output current. This device delivers up to 1.5A output current with a low dropout voltage of 0.435V at its maximum rated current. The output voltage is adjustable from 1.23V to 6.6V, providing flexibility for various power supply designs. Key protection features include over-current, over-temperature, and short-circuit protection. The regulator offers a power supply rejection ratio (PSRR) ranging from 73dB to 57dB across a frequency range of 120Hz. It operates from an input voltage up to 7V and features an Enable pin for power sequencing. The LP3855EMP-ADJ is supplied in a SOT-223-5 package, suitable for surface mounting. This component is commonly employed in telecommunications, automotive, and industrial systems.
